A. A triangle with three congruent sides is equiangular.

B. The Isosceles Triangle Theorem can be applied to equilateral triangles.

C. The measure of each angle of an equilateral triangle is 120°.

D. A triangle with three congruent angles is equilateral.

Answer 1

Answer: C

Because a triangle can only equal up to 180 degrees

Answer 2

A triangle is a polygon with three sides and three angles. Types of triangles include scalene, equilateral, isosceles.

An equilateral triangle is a triangle in which all (three) of its sides are congruent. Also, all the angles are congruent. Each angle in an equilateral triangle measures 120°

An isosceles triangle is a triangle in which two of its sides are congruent. Also, two angles are congruent. The Isosceles Triangle Theorem states that If two sides of a triangle are congruent, then angles opposite those sides are congruent.

The Isosceles Triangle Theorem also holds for an equilateral triangle
