- 9.4.1 If a tangent and a secant (or chord) intersect on a circle at the point of tangency, then the measure of the angle formed is half the measure of its intercepted arc.
9.4.2 The measure of an angle formed by two secants or chords that intersect in the interior of a circle is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
9.4.3 The measure of an angle formed by two secants that intersect in the exterior of a circle is half the difference of the intercepted arc.
Here is tonight's homework: pages 592-593, questions 1-8. (The first four questions are really just asking what the theorems say, so look at the wording in your book carefully.)

The link is on the post labeled "The doctor says..."
It is towards the end where it says "here is the link."
