If triangle R'S'T' is a dilation of triangle RST, what would be the rest of the coordinates for triangle R'S'T?

Question

R (-2,-3)
S (0,2)
T (2,-3)

R'(-6,-9)
S'( , )
T' ( , )

Answer 1

A dilation is basically the opposite of a contraction. So you can see that the first coordinate pair has increased by a factor of 3 from one triangle to the next. Therefore, do the same to the other coordinate pairs.

S'(0*3,2*3) = (0,6)
T'(2*3,-3*3) = (6,-9)

Hope this helps!
