Triangle midsegment theorem: The midsegment of two sides of a triangle is to the side and is half as long. Slide 14 Instruction Proving the Triangle Midsegment Theorem FIND THE COORDINATES OF D AND E D E A B C If DEis a midsegment, then DE∥ and DE= BC. Given: Dis the midpoint of AB; Eis the midpoint of AC. Prove: DE=1 2 BC x y B(0, 0) Thus, by first proving that the two triangles are similar and applying the similarity ratio between triangles, we determined that the perimeter of 𝑌 𝑀 𝐶 is 48 cm. In the previous example, we saw how there was a pair of similar triangles created by parallel lines and a transversal within the rectangle.

The SSS similarity criterion says that two triangles are similar if their three corresponding side lengths are in the same ratio. That is, if one triangle has side lengths a, b, c, and the other has side lengths A, B, C, then the triangles are similar if A/a=B/b=C/c. These three ratios are all equal to some constant, called the scale factor.
