Question

what type of polygon is shown? convex heptagon concave heptagon concave octagon convex octagon

Explanation:

Step1: Count the number of sides

A heptagon has 7 sides, an octagon has 8 sides. The given polygon has 7 sides.

Step2: Determine convex or concave

In a convex polygon, all interior angles are less than 180 degrees and all diagonals are inside the polygon. In a concave polygon, at least one interior angle is greater than 180 degrees. The given polygon has an indentation (a reflex angle), so it is concave.

Answer:

concave heptagon
