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? (1 point)

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'.

When a dilation of a polygon happens only the angles are alike between the 2. So this would rule out B and D. `dilations change the length and the position of the shape`

Since PQRST is dilated to P`Q`R`S`T` this would mean P`Q`R`S`T` is `3 times` bigger than PQRST (looking at the image). How would you display this as a ratio?
