Question

A polygon with 7 sides is shown. An angle goes inside of the shape.
What type of polygon is shown?

convex heptagon
concave heptagon
concave octagon
convex octagon

Answer 1

A polygon with 7 sides is called a heptagon. If an angle goes inside of the shape, it indicates that at least one of the interior angles is greater than 180 degrees, which means the polygon is not convex. Therefore, the correct answer is:

**concave heptagon.**
