Explain why the following statement is true. Each interior angle of an equiangular triangle measures 60 ∘ .

To determine

Whether the statement is true.

Explanation

The angles of the equiangular triangle are equal to each other.

The sum of the three angles in a triangle is 180°.

Calculation:

Assume the angle of the equiangular triangle be mA, mB and mC.

Calculate the each angle of the equiangular triangle.

mA+mB+mC=180°(1)

Since, the angles of the equiangular triangle is equal to each other then,

mA=mB=mC
