Answer:
Letter C (Regular Polygons) is the answer.
Keynotes:
- All regular polygons have equal sides and angles.
(ex. equilateral triangle, square, octagon)
- Irregular polygons are polygons that have unequal lengths and/or unequal angles on its sides.
(ex. isosceles triangle, rectangle, right triangle)
- Congruent polygons are two or more polygons (in comparison) that have the same physical characteristics with one another, and such of these are the same quantities of sides, interior angles, size, and the shape itself. All of these needs to be strongly considered if you are identifying whether polygons are congruent or not.
