Similar triangles worksheet.

Theorem If two angles of one triangle have the same measure as two angles of another triangle, then the triangles are similar. In Figure 3, ΔABC is similar to ΔDEF since ∠A = ∠D and ∠C = ∠F . In symbols, we write ΔABC ~ ΔDEF .Similar Figures 1 Introduction Similar triangles are fundamentals of geometry. Without them, it would be very di cult in many con gurations to convert angle information to length information (e.g. through AA similarity) and vice versa. At the same time, though, similar triangles are often the most di cult things to spot without prior geometric ...Triangles EFG and QRS are similar. The length of the sides of EFG are 144, 128, and 112. The length of the smallest side of QRS is 280, what is the length of the longest side of QRS? (draw a diagram and solve) 4.
