Question

1. what is the shape shown? a concave nonagon a concave heptagon a convex pentagon a convex hexagon

Explanation:

1. First, count the number of sides of the polygon. The shape has 5 sides, so it's a pentagon (since pentagon has 5 sides, nonagon has 9, heptagon has 7, hexagon has 6).
2. Then, check if it's convex or concave. A convex polygon has all interior angles less than 180 degrees and all vertices pointing outwards. The given shape's vertices all point outwards, so it's convex.

Answer:

A convex pentagon
