Keegan says that a quadrilateral is a square if and only if it is a rectangle. Is this a true biconditional statement? For my math imagine users, the answer is No, because all rectangles are not squares.

answer: (3,11) is your answer.

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
