Question

What is the measure of all seminary of an Equilateral triangle?

a) 30^∘
b) 45^∘
c) 60^∘
d) 90^∘

Answer 1

The measure of all angles in an equilateral triangle is 60°.

Step-by-step explanation:

An equilateral triangle is a triangle in which all three sides are equal in length. Therefore, all three angles of an equilateral triangle are also equal in measure. Since the sum of all angles in a triangle is 180 degrees, each angle of an equilateral triangle measures 60 degrees. Therefore, the measure of all angles in an equilateral triangle is 60°.
