Triangle angle theorem

When Side A= Side B, Angle A= Angle B and vice versa, I know this works in rectangles squares and triangles. Can anyone give me more shapes where this theorem works? Or does it work for every shape or just for those shapes? Can you help me?

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.

This only works in triangles, and not in quadrilaterals even

Thank you

I think it works in all regular polygons.

By definition they have equal angles and equal side lengths, so yeah it works
