Objectives: -Identify and use the Parallel Postulate and the Triangle Sum Theorem Warm-Up: Position one letter in each of the five openings. Do this in such a manner that three numbers are spelled out that total thirteen. Words may be written clockwise and counterclockwise, and individual letters may be shared.
2
The Parallel Postulate: Given a line and a point not on the line, there is one and only one line that contains the given point and is parallel to the given line.
3
The Triangle Sum Theorem:
4
Exterior Angle Theorem:
5
Example: Two angle measures are given. Find the missing angle measure or state that the triangle does not exist.
6
Example: A D B E F C
