# Similar Triangles, Part 2 - Khan Academy

Video uses an electronic black board with different-colored pens. In this video. Mr. Khan discusses the measurement of alternate interior angles, corresponding angles and how they are similar. Triangles are drawn in two parallel lines and a transversal. Narrator shows how to figure out the length of the sides of the angles when three sides are known. Good quality video. Good for middle elementary and middle school students.
