Question

A choice matrix is shown. Complete the choice matrix by selecting the category which best transformations would preserve the lengths of the sides of a quadrilateral ifall vertices of the quadrilateral undergo the same transformation. Answers may be used more than once.

Answer 1

The translation and reflection transformations only preserve the length of sides.

Hence, only the transformations (x,y)-->(x-3, -y+2) and (-x+6, -y-8) preserve length.

In rest of the transformations, the coordinates (x,y) are multiplied by a constant which results in dilation of the quadrilateral. It will not preserve length.
