Question

These triangles are NOT similar! Why not?
Use calculations AND words to explain.

Answer 1

They aren’t the same due to the fact that they have different length and size. They have different numbers and letters to show you that the triangles are not similar due to size.

Answer 2

if ΔPQR ≈ ΔSTU =>

=> PQ/ST = PR/SU = QR/TU

9/7 = 12/8 = 15/10

9×8 = 7×12

72 = 84 (false)

=> ΔPQR ≠ ΔSTU
