There are 360 degrees in a circle. Half of a circle is called a semicircle, and it contains 180 degrees. Whereas there are four quadrants in every circle, there are two semicircles.

The diameter of a circle is a straight line passing through the circle's center and touching the circle at each end. A circle with a horizontal line of diameter and a vertical line of diameter drawn is divided into quadrants. With only one diameter drawn, the circle is divided into semicircles.
