Question

Hannah drew a pattern using only equilateral triangles. Which of the following statements about an equilateral triangle is true?
A) the measure of each angle is 60 degrees
B) the measure of each angle is 120 degrees
C) the measure of one of the angles is 90 degrees
D) the measure of one of the angles is more than 180 degrees

Is the answer A?

Answer 1

A) The measure of each angle is 60 degrees.

An equilateral triangle has equal angles of 60 degrees and lengths (of sides). 

Answer 2

The sum of the angle of a triangle is 180 degrees. It is mentioned that Hannah drew a pattern of equilateral triangles. Equilateral triangle has three equal sides. Also, its angles are the same, having 60 degrees at each corner of the triangle. The answer is a. Letter b does not qualify to be an equilateral triangle because 120 degrees times 3 is greater than 180 degrees. Letter c and d exceeds the total number of angles at 180 degrees.
