# Repeat?!

Why is it that for problem 1 and 4 in level 3 Geometry that they are essentially the same problem?

[Clarification: Note that not everyone receives the problems in the same order, or must have received these problems. We are referring to [chord in a semicircle](https://brilliant.org/i/3Knb5M/) and [four points on a semicircle](https://brilliant.org/i/lhsb38/). - Calvin]

The ratios are different. In the 1st problem, the ratio is $$1: 2$$, which allows for a 1 line solution.

In the 4th problem, you're asked to consider the more general case, where I used a ratio of $$1: 4$$. Of course, you can use the same generalized approach to solve the first problem.

no..they are slightly different..observe carefully..

Hmm well I used exactly the same methods to solve them

I got chord in a semicircle in level 2 geometry,and it was a 40-pt question.Why?

This is also the same as this question: https://brilliant.org/i/IRMRjd/

how are they same?
