4 2 study guide and intervention angles of triangles

The first step in writing a coordinate proof is to place a figure on the coordinate plane and label the vertices. Use the following guidelines. 1. Use the origin as a vertex or center of the figure. 2. Place at least one side of the polygon on an axis. 3. Keep the figure in the first quadrant if possible. 4..

To prove the Inscribed Angle Theorem, you would need to split it up into three cases, like the three different angles drawn from Investigation 9-4. We will touch on the algebraic proofs in the review exercises. Example 1: Find mDCcand m6ADB. Solution: From the Inscribed Angle Theorem, mDCc=245 =90 . m6ADB =1 276. =38 .6-1 Study Guide And Intervention Angles Of Polygons Hey there, fellow learners!
