By your response I thought what you have thought about me. So I request you not to judge me on my age coz I m still 14 although it is showing 22. I do hope there will not be any clashes in b/w us in the future. I m also sorry for being rude to you and I too hope you feeling the same way.Log in to reply

No worries. On Brilliant, because the problems are much harder than what one would normally encounter, it is very common for mistakes / misconceptions to occur. The important thing is to learn from the mistakes and understand why you had made them, and how to avoid them in future.

No one is exempt from making mistakes, me included. I have had posted numerous problems where I got corrected by the community. For example, I had a problem in which I made numerous mistakes which let to all kinds of wrong conclusions. @brian charlesworth came along and helped me fix the problem, which led to this gem.

In fact, I do not know of any avid problem creator who has not had at least one valid report submitted against his problem. Eventually, they get fixed, and the community appreciates their efforts. – Calvin Lin Staff · 2 years ago

Oh Skanda , I happened to see this problem click here. The answer to this problem is wrong , infact Jon Hausmann has given proof to prove it false. I saw that you are one of its solvers.I am very curious to know its method. Can you explain to me how you arrived at this answer? That would be helpful .. thanks! – Nihar Mahajan · 1 year, 11 months ago

Sir , I am damn sure that he would not be able to post a solution , because he didn't solve it , he obtained the answer by cheating. Also , he could have realized that the problem has faults , and he might have written a report , if in indeed he had solved that problem.Log in to reply

@Calvin Lin 's records clearly indicate that you are a 'cheater' and a 'lier'. Also you cannot provide solution to a problem which you solved 'too easily'. which means you did't solve that problem by yourselves and you got the answer by cheating! – Nihar Mahajan · 1 year, 11 months ago

Skanda Prasad please follow the guide lines below to write a link.

1) Firstly open the square brackets i.e, [ . . . ]

2) Next, write something in it. example [here]

3) Next go to the page where you want to connect this link. For example if you want to connect the link to you Sound problem, go to that page

4) Next, copy the URL written on the page. For example, in this page the URL can be found above(i.e, https://brilliant.org/discussions/thread/skanda-prasads-message-board/).

5) Now, open curved brackets i.e, ( . . . )(i.e, [here] and beside it, without space( . . . ))

6) Finally copy the URL in to the curved brackets and click post or preview to see it in

GREENS!For example, I've made a link to your Sound-2 problem, click here – Sravanth Chebrolu · 2 years agoLog in to reply

With reference to your problem and problem, here is the proof that in

anycyclic hexagon, \( \angle A + \angle C + \angle E = 360 ^ \circ \). It is independent of BDF being an equilateral triangle, which is not stated in the question, and cannot be used as an assumption in the problem.Solution:Say the (not necessarily regular) hexagon is ABCDEF. Then, \( \angle A = 180 ^ \circ - \angle FDB \), \( \angle C = 180 ^ \circ - \angle BFD \), \( \angle E = 180 ^ \circ - \angle FDB \).Hence, \( \angle A + \angle C + \angle E = 540 ^ \circ - ( \angle FDB - \angle BFD - \angle FDB ) = 540 ^ \circ - 180 ^ \circ = 360 ^ \circ \).

I do not abuse the power of being staff. Note that Jon Haussmann's dispute echoes mine. I have stated out the reasons for why your problem was deleted. Specifically, the 2 issues are:

In your question you did not state that \(DEF\) is an equilateral triangle, as such that cannot be used in the solution. It is an unwarranted assumption, and hence a solution of "Let's assume this fact" is not a correct solution.

There are multiple ways to prove a fact. It is not reasonable to use MCQ to say "You can only prove this problem in this certain way". For example, I could have used a lot of parallel lines to show that the sum of those angles is 180, instead of using triangle \(BFD \).

As such, the answer of "By construction proving triangle is equilateral and then by cyclic quadilateral property" is not correct because it is a false statement. – Calvin Lin Staff · 2 years ago

I am 100 % sure that it is accurate question and with a valid answer. As you would have noticed, I have posted my solution. If you prove that it is wrong, I will also stop posting this question again and again.Log in to reply

By construction, OB=OD=OF.

If you use a little of your brains, you might understand that BDF is now an equilateral triangle, by the isosceles triangle property of triangles OFD, OBD and OBF.

Hence all angles are equal in the triangle BDF as OB, OF, OD are the radii of the circle.

Now consider the quadrilateral DBAF, As angle B = 60 degrees, angle A = 120 degrees.

In the same way, it can be proved for the angles, C and E – Skanda Prasad · 2 years ago

Can you explain the following diagram them?

If you have any confusion with the fig. then pls check my problem known as " Geometrically Brain teasing Problem by Skanda Prasad" where you will get the fig. and clear the confusions, if you had had any.... Thank You Sir !!!!Log in to reply

Unless, the figure is trying to say that Angles A , C ,E are equal, in which case that should be clearly stated in the problem. And if so, then ABCDEF is a regular hexagon, and so there are 2 possible answers to your problem. – Calvin Lin Staff · 2 years ago

Log in to reply

Consider the quadrilateral DBFE, as angle DBF = 60 degrees, angle DEF = 120 degrees

Consider the quadrilateral DCBF as angle DFB = 60 degrees, angle DCB = 120 degrees

Hence Angles A + C + E = 120+120+120 = 360 – Skanda Prasad · 2 years ago

For your information Sir, I have "proved" that BDF is an equilateral triangle just now , which you had rejected before. Remember?? Sir??Log in to reply

I have also said that OD is "also" the radii of the circle. But the figure you have given does not have OD as radii. Does it ? Sir ???Log in to reply

– Calvin Lin Staff · 2 years ago

B, D, F are points on the circumference, so OB, OD, OF are all radii of the circle. So yes, OD is a radii. It is just not drawn in as yet.Log in to reply

I was just surfing in your message board. You had changed a person's age..... Is it possible for mine too, Sir?? Could you please change it as 14 from 22 ??Log in to reply

– Skanda Prasad · 2 years ago

Also note that there is no O in the diagram you have just posted....Log in to reply

Hence they are equal. Simple!! Isn't it Sir??

And also note that O is the centre of the circle. therefore radii are the same in the circle....!!!!!!

I have no pleasure in explaining the diagram because it is not the one related to my problem – Skanda Prasad · 2 years ago

Log in to reply

Yes, OB = OD = OF as length. In the diagram, I have given you points O, B, D, F such that OB = OD = OF. But BDF is not an equilateral triangle.

Note that even though OB= OD = OF, this does not imply that BD = DF = FB, which is necessary to show that it is an equilateral triangle. – Calvin Lin Staff · 2 years ago

Log in to reply

Consider traingle ODF OD=OF Hence angle ODF=OFD

But angle ODB=ODF and angle ODB+ODF= angle BDF

In the same way we can take the triangles OBF OB=OF Hence angle OBF=OFB

angle OFD+OFB=angle DFB

HENCE angles BDF = BFD = DBF (in the same way) AS ALL ANGLES IN A TRIANGLE ARE EQUAL, THEIR SIDES ARE EQUAL AND HENCEFORTH CONSIDERED TO BE AN EQUILATERAL TRIANGLE. – Skanda Prasad · 2 years ago

Log in to reply

Log in to reply

Here's the proof...

Consider the triangle ODB in which angle ODB=OBD

Consider triangle ODF angle OFD=ODF

Come on!! you must know that the equal radius bring equal base angles.

Hence, angle ODB in the triangle OBD and angle ODF in triangle OFD have the same measures.

in the same way, if you add angles OFD and OFB you will get Angle DFB if you add angles OBF and OBD you will get angle DBF when all the angles in a triangle are equal, it is an equilateral triangle

IT IS TRUE FOR ALL SUCH ANGLES IN THE FIG. HENCE IT IS AN EQUILATERAL TRIANGLE. – Skanda Prasad · 2 years ago
