Section 3.5: Parallel Lines and Triangles      Objective:

Triangle Angle-Sum Theorem:
Example 1) Solve for x, y, and z in the
figure below

Example 2) What are the values of x and y in the
diagram.

Example 3) How many distinct triangles are
represented in the diagram above?

Exterior angle: angle formed by a side
and an extension of an adjacent side.
Remote interior angles: 2 nonadjacent
interior angles corresponding to each
exterior angle of a triangle

Example 4) What is the measure of          ?
