Question

1. an equilateral triangle is also an equiangular triangle. true false 14. in an isosceles triangle, what do we call the angles that have the same measure? apex angles central angles base angles vertex angles

Explanation:

Question 13

An equilateral triangle has all three sides equal. By the properties of triangles, if all sides are equal, then all angles are equal (each angle is \(60^\circ\)). An equiangular triangle is defined as a triangle with all angles equal. So an equilateral triangle is also equiangular.

In an isosceles triangle, the two sides that are equal are called the legs, and the third side is the base. The angles opposite the equal sides (and adjacent to the base) are called the base angles, and these two angles are equal in measure. Apex angle is the angle opposite the base (the unequal angle in a non - equilateral isosceles triangle), central angles are related to circles, and vertex angle can be a general term but in the context of isosceles triangles, the equal angles are base angles.

Answer:

True
