Step-by-step explanation:

An angle divides a plane into three  regions

plane :

A flat surface that is infinitely large and with zero thickness

Angles separate their plane into three regions: the angle; the region inside or interior to the angle; and the region outside or exterior to the angle.

For angles of measure between 0° and 180°, the interior is the convex set. A ray which extends from the vertex of an angle through the interior such that it divides the angle into two congruent (same shape and measure) angles is called an angle bisector. Bisect means to cut into two equal pieces.
