Lesson 7.4 7.5 applying properties of similar triangles this example uses the two transversal proportionality corollary that we will learn about in today's lesson. So, all of the transversal parts will be proportional with each other. ex) because line gj is a transversal of three lines and line km also is a transversal of the same three lines, all parts of the transversals are proportional. =01 12 =3 4 = 5 so the missing part of the transversal is equal to 8x = 60, so x = 7.5.
