Question

Triangle PQR has coordinates P(2,4),(-2,4), R(0,-6). Write the coordinates of the vertices of theimage of a triangle after a dilation of 1.5.

Answer 1

Triangle PQR has coordinates P(2,4),(-2,4), R(0,-6). Write the coordinates of the vertices of the

image of a triangle after a dilation of 1.5.

i will assume that the center of dilation is the origin (0,0)

so

the rule of the dilation is

(x,y) ------> (1.5x, 1.5y)

therefore

the vertices of the image are

P(2,4) ------> P'(3,6)

Q(-2,4) -----> Q'(-3,6)

R(0,6) -----> R'(0,9)
