Find measure of vertical angles | Angles and intersecting lines | Geometry | Khan Academy


By KhanAcademy

Now that we've learned about complementary and supplementary angles, let's use algebra to find the measure of vertical angles, or angles opposite each other when two lines cross.

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


By 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.
