Question

Part A: Is it possible to make a triangle that is both equilateral triangle and a right triangle? Explain

Part B: Is it possible to draw a triangle with side lengths of 15, 15 and 20? Explain.

Answer 1

A. No, it is not possible. An equilateral triangle is also an equiangular triangle, meaning all of its angles measure 60°.

B. Yes, it is possible. By the Triangle Inequality Theorem:

15 + 15 > 20, and 20 + 15 > 15
