If AB = BC = CA, what is m1?

Alborosie

Answer:

60°

Step-by-step explanation:

All the side lengths of the triangle have the same measurement. This makes it an equilateral triangle. By the definition of an equilateral triangle, all the angles are congruent, therefore all their measurements are the same. There are 3 total angles in a triangle, and the total sum of the angel measurements of a triangle is 180. Divide 180 with 3:

180/3 = 60

60° is your answer.
