Question

Can anyone cleanly explain the Exterior Angle to a Circle Theorem to me? Or a link or a pic...thank you :)

Answer 1

Exterior Angle to a Circle Theorem

I am not familiar with that theorem by that name.

Do you have a statement of the theorem?

Answer 2

ditto

Answer 3

"Exterior Angle to a Circle Theorem
If two secants, two tangents, or a secant and a tangent intersect outside a circle, the measure of the created angle between them is one-half the absolute value of the difference of the measures of their intercepted arcs."

Answer 4

smells like tangent and secant lines to a circle though

Answer 5

Over half that vocab is over my head

Answer 7

so-called the "far arc near arc theorem" rather

Answer 8

but you can pretty much see what that is there

Answer 9

OH okay! Thank you :D
