7.

A regular polygon has sides with the same length and interior angles with the same
measure. What kind of triangle is also a regular polygon?


A right triangle
B obtuse triangle
C scalene triangle

D equilateral triangle
E isosceles triangle

Answer 1

A regular polygon has sides with the same length and interior angles with the same measure. Therefore, a regular polygon is a polygon with all sides and angles equal.

An equilateral triangle is also a polygon with all sides and angles equal. Therefore, an equilateral triangle is a regular polygon.

So, the answer is option D: equilateral triangle.

Answer 2

D equilateral triangle.

Explanation:

An equilateral triangle has three sides with equal length and three interior angles with the same measure of 60 degrees. Therefore, an equilateral triangle can also be considered as a regular polygon with three sides.
