Answer 1

• octagon
• irregular polygon
• concave

Explanation:

The figure has 8 sides that are each line segments joined at the ends. An 8-sided polygon is called an octagon. Though the sides are the same length, not all angles are congruent, so the polygon is not a regular polygon. Some of the angles are reflex angles, so the polygon is concave, not convex.
