Triangle calculator - Open in Google Chrome.

(Triangles online calculator developed by Jesus S.)


I propose this free online calculator triangles without advertising to help students with geometry, not exercising, because their calculations formulas are not displayed. It is designed in a didactic way to check and view the

TrianCal is online calculator triangles that works with any combination of values including sides, heights, angles, the area or perimeter of any triangle, calculating it with the minimum possible value (typically three).

Other functions:

  • Draw the triangle(s) with GeoGebra.

  • Set the range of values allowed into each element.

  • The type of angle.

  • The type of triangle by its sides and angles.

  • Selection of language (English or Spanish).

  • Select and angles [degrees (°), Radians, Degrees, minutes and seconds (°
    '") or degrees and minutes (°')] is.

  • Number of decimal places to show in the results (0-15).

  • You can use the arrow keys and the Tab key to navigate through the

  • Drop-down menu to select values comfortably.

  • Create a link (URL) to the current triangle.

  • An icon mail to communicate with the author.

NOTE: You must use the Google Chrome browser to display correctly TrianCal.

Examples of possible combinations:

  • The area, perimeter and other data (side, height or angle), if the outside
    equilateral triangle would not need the third data.

  • 2 angles and other data (if the value of the other data is not put aside
    the value of "a" at the time of drawing the triangle is 10).

  • One hand, one high and one angle.

  • 3 heights.

  • 3 sides.

  • 2 heights and perimeter.

  • Any other combination of values.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Have you tried sharing it on Reddit? I think it would be extremely beneficial to promote your site there.
