Question

drawing draw a figure that fits the description.

1. a concave nonagon

Explanation:

A nonagon is a 9-sided polygon. A concave polygon has at least one interior angle greater than 180° (a "reflex" angle), causing the polygon to "cave in" at that vertex. To draw it, create 9 connected line segments where at least one vertex bends inward to form a reflex angle.

Answer:

A concave nonagon is a 9-sided polygon with at least one interior angle measuring greater than 180° (a reflex angle). A simple representation can be described as:

1. Draw 8 connected line segments forming a mostly convex shape.
2. At one vertex, instead of bending outward, bend the segment inward to create a reflex angle, then connect the final segment back to the starting point to close the 9-sided figure.

(Visual: A 9-sided shape where one side dips inward, creating an indentation, while the rest of the sides form a roughly convex outline.)
