Question

find the size of each angle of equilateral Triangle ​

Answer 1

Step-by-step explanation:

all the side of the equilateral triangle will be equal. For example if one side of the triangle is 3 than all the side of the equilateral triangle will be 3.

Answer 2

Since, all the sides of an equilateral triangle are equal therefore the angles containing it must also be equal.

That is, Angle(A) = Angle(B) = Angle(C) = m° (let)

Also, sum if all the angles of a triangle = 180°

=> A + B + C = 180°

m + m + m = 180°

3m = 180°

m = 60°

That is, Angle(A) = m° = 60°

Angle(B) = m° = 60°

Angle(C) = m° = 60°

Thus, All angles of an Equilateral triangle measure 60° each.
