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

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

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

Dilations change side length by the scale factor, but the angle measures remain unchanged.

puzzler7 · Answer

A is wrong because the length of PT is changed by the dilation.
C is wrong because the length is changed by the dilation.
D is wrong because the angle is not helped by the dilation.
