A triangle has one angle that measures 60° and another that measures 60°. What kind of triangle is it?
Question
A triangle has one angle that measures 60° and another that measures 60°. What kind of triangle is it?
Solution
This is an equilateral triangle. In an equilateral triangle, all three angles are equal. Since the sum of angles in a triangle is 180°, and we already know two angles are 60° each, the third angle must also be 60°. Therefore, the triangle with all angles measuring 60° is an equilateral triangle.
