Name each regular polygon. find the measure the indicated angles

ANSWER

i. 180°

ii. 60°

iii. 360°

iv. 120°

EXPLANATION

The given regular polygon has 3 sides.

Since all the three sides are equal, it is called an equilateral triangle.

The sum of interior angles of an equilateral triangle is 180°

One interior angle is 60° because all the three angles are equal.

The sum of exterior angles is 360°

One exterior angle is 120° because all the three exterior angles are equal.
