Proof. Consider the dilation with center C and scaling factor CA/CD
... Consider a dilation (choose any center you like) with scaling factor XY /AB. Apply this dilation to ∆ABC to get triangle A1 B1 C1 . Angle measures are preserved, so m6 A1 = m6 A = m6 X, and m6 B1 = m6 B = m6 Y . Due to the choice of scaling factor, A1 B1 = XY . By SAS congruence, ∆A1 B1 C1 ∼ = ∆XY Z ...

10.2 Diagonals and Angle Measure
... Activity: Have three come up and each hold a point in a length of yarn. Teacher explains the measure of the external angles of a polygon is from the direction on one side of the polygon to the direction of the next leg or side. Can be thought of as walking around the polygon. Walk around the trian ...
