# Angles Formed by Intersecting Secants Outside of a Circle

Intersecting Secants Outside of a Circle

The central angles tell us what about the arcs?

Take the difference of the arcs. What do you notice about the measurement of the angle outside the circle and this difference?

## Angle formed by Secants Theorem

Fill in the blank:
*If two secant segments intersect at a common point
outside of a given circle, then the angle formed outside of the circle equals
