Question

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

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

Which statement about polygon PQRST and its image after dilation, polygon P'Q'R'S'T', is correct? (1 point)

The length of side PT is equal to the length of side P'T'.
The measure of angle T is equal to the measure of angle T'.
The length of diagonal RT is equal to the length of diagonal R'T'.
The measures of angle P and angle P' are in the ratio 1:3.
