Question

Rectangle ABCD is shown below with line EF passing through the center:

If rectangle ABCD is dilated by a scale factor of five about the center of the rectangle to create rectangle A'B'C'D', dilated line E'F' will

A: be parallel to the original line
B: shift five units to the right
C: be perpendicular to the original line
D: lie on the same line as the original

Answer 1

D lie on thesame line as the original

Explanation:

I took the test and hurray! It was correct

Answer 2

Dilation of rectangle ABCD by a given scale factor about the center of rectangle to create an image, will not affect the image of the EF which is E'F', this is because line EF is passing through the center of the rectangle, the point at which the rectangle was dilated. Thus the answer will be:

D: lie on the same line as the original
