Question

Polygon PQRST shown below is dilated with a scale factor of 3, keeping the origin as the center of dilation:

Two polygons are drawn on a coordinate grid. Polygon PQRST has vertices at P 0 and negative 3, Q 3 and negative 2, R 3 and 1, S

Which statement about polygon PQRST and its image after dilation, polygon P'Q'R'S'T', is correct?

Answer 1

shown where ?

Answer 2

The lengths of side RQ and side R'Q' are in the ratio 1:3.
The length of diagonal RT is equal to the length of diagonal R'T'.
The measures of angle S and angle S' are in the ratio 1:3.
The length of side PQ is equal to the length of side P'Q'.

Answer 3

for choice one do you can numerate the units from the length of RQ and R'Q' on this diagram ?

Answer 4

and see what ratio will get ?
