Question

Sasha has a triangle with vertices a,b and c. The triangle has three congruent angles. She wants to show that triangle ABC has three congruent sides, but she does not have a ruler to measure the lengths of the sides. How can she show that line triangle has three congruent sides?

Answer 1

If she has a protractor then she could measure the angles, if they are all the same, then the sides are congruent. It also means that the triangle is an equilateral triangle. (each angle should be 60 degrees) Without somthing a ruler or a protractor though, there is no way to know for sure.

Answer 2

She can draw a triangle and then write the lenghts of the triangles with the same numbers
