8.5 Three Theorems Involving Proportions (Lesson)


By AutenMath

A lesson on the Angle Bisector and Side Splitter theorems and a theorem relating segments cut by two transversals and three or more parallel lines.

This lesson covers parallel lines. Students learn that if two parallel lines are cut by a transversal, then corresponding angles are congruent, alternate interior angles are congruent, and same-side interior angles are supplementary. Students are then asked to find missing values based on these concepts.

Figuring out angles in a triangle. A little about exterior angles being the sum of the remote interior angles

Angles (part 3) | Angles and intersecting lines | Geometry | Khan Academy

This video uses an electronic black board with different colored pens. Angles formed with two parallel lines (defines parallel lines) and a transversal line (a line that crosses the two parallel lines). The video then goes into labeling the various angles, corresponding angles, opposite angles, alternate interior angles, alternate exterior angles, and supplementary angles. The last thing the video explains is that all the angles in a triangle add up to 180 degrees. It shows how to find the measurements of each of these angles. Good video for review of concepts and angle vocabulary. Good for middle school students.
