(Click on image to enlarge.)
This program teaches the student how to calculate the measures of the chords, arcs, angles (central, inscribed, chord-tangent, chord-chord, secant-secant, secant-tangent, tangent-tangent), common tangent length and inscribed quadrilaterals.
The topic of "Circles" in high school geometry is one of the most challenging. There are over 50 theorems and definitions to learn about "Circles" and the topic is a very favorite of college placement exams such as the S.A.T. and A.C.T.
This program contains detailed charts which can be printed and used as study guides. Vocabulary quiz in addition to the test. (Includes a contest section.)
