Hello, Hthornton!

Problem 1. http://i42.tinypic.com/2ikusjn.jpg

I need to find measures of angles: .(a) BAC . (b) ABD . (c) DBC

I was also suppose to find measure of arc AD

. . and I found it to be 56, is that correct? . Yes!

Theorem: An inscribed angle is measured by one-half its intercepted arc.
