Today we went over the handout given out after the quiz yesterday. It applied the theorems from section 9-4 on inscribed angles.
KNOW:
1) the measure of inscribed angle = the HALF the measure of its intercepted arc
2) if inscribed angles intercept the same arc (or congruent arcs) then they are congruent
3) if an inscribed angle intercepts a semicircle, then it is a right angle
4) if a quadrilateral is inscribed in a circle, then its opposite angles are supplementary.
NEW SECTION ON TANGENTS:
Today we looked up the definitions for:
1) tangent (line to a circle)
2) point of tangency
3) interior/exterior of a circle
4) common tangent
5) common interior tangent; common exterior tangent
6) circumscribed polygons
