Triangle Side-Splitting Theorem. Geometry-Dilations and Scale Factors
Description
In this video we'll learn how to use the triangle side-splitting theorem to find the lengths of the sides of a triangle. The theorem tells us that, when we place a line segment inside a triangle which has its endpoints on opposite sides of the triangle and which is parallel to the side it doesn't touch, then we can set up a proportion between the lengths of the sides of the smaller triangle and the lengths of the sides of the bigger triangle.
