Question

Triangle XYZ has been enlarged and P as the center of dilation and scale to form a triangle X’ Y’ Z’

Answer choices:

A. X’P/ XP =Y’P/YP= Z’P/ZP
B. X’Y’Z’ = XYZ
C. X’X = XP, Y’Y = YP, Z’Z = ZP
D. X’X = Y’Y = Z’Z

Answer 1

Distances from the center of dilation are multiplied by the dilation factor. The appropriate choice is ...

... A. X'P/XP = Y'P/YP = Z'P/ZP

_____

We don't know what selection B means in this context.

Selection C will only be true if the dilation is by a factor of 2.

Selection D will only be true if P is the center of the circumscribing circle for both X'Y'Z' and XYZ.
