Angle Angle Similarity

OBJECTIVE:I will be able to prove two triangles are similar by the Angle - Angle Similarity Postulate

Triangle RST is the dilation of Triangle ABC under scale factor "d". Change scale factor d by sliding the point to show different values. Explain what happens to the angles when you change the scale factor.Explain what happens to the triangles. Drag either points A, B, or C around the screen. Explain what happens to the scale factor d. Explain what happens to angles.
