Question

Figure is a closed curve entirely made up of line segments. The another name for this shape is ___.

Answer 1

Identify the shape

A curve made entirely of line segments is called a polygon.

A concave polygon is a polygon that has at least one exterior angle less than $180°$

A convex polygon is a polygon that exterior angles are greater than $180°$.

Since $\angle C$ and $\angle F$ are less than $180°$, the figure is concave.

Hence, another name for this shape is concave polygon.
