It should be noted that in a circle theorem, the angle that's at the center of the circle is twice the angle at the circumference.
Circle theorem.
An overview of the circle theorem will be given as your information is incomplete. The angle that's in a semicircle is a right angle.
Also, the angles that are in the same segment are equal. Furthermore, the opposite angles that are in a cyclic quadrilateral equal 180°. The angle between the tangent and the radius is also 90°.

A theorem that was not taught was The angles in the same segment from a common chord are equal. I don't really find any theorems that we did learn similar to this one. This theorem could be used in a real world application to see if the angles are equal on a line segment in a circle; for example, someone has to find out if the rims of a tire will all have the equal angles so the tire can move properly.
