Circle Theorem 1

When a radius meets a tangent, the angle will always be 90°.

New cards

13

Circle Theorem 2

From a point outside a circle two tangents can be drawn. From a point to where they touch the circle, the two tangents are equal in length

New cards

14

Circle Theorem 3

The angle at the center of a circle is twice the angle at the circumference.

E.g. The 2x angle is double the x angle
