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

# Triangle angle example 1 | Angles and intersecting lines | Geometry | Khan Academy

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.

# Angles of Parallel Lines - Khan Academy

Angles of a transverse line when you intersect parallel lines are discussed in this video. Video discusses parallel lines and what a transverse line is. Video then goes into labeling the angles, such as corresponding angles, opposite angles, alternate interior angles, alternate exterior angles, and supplementary angles. The video shows how to find the measurement of each of the angles using what you know about angles and lines. Good review for concepts of angles and vocabulary associated with angles. Good quality video. Good for middle elementary and middle school students.
