Question

Use the drop-down menus below to state the sequence of transformations that maps Figure K onto Figure L in the animation below. Then use those transformations to determine: are the two figures congruent? Use the drop-down menus to explain why or why not.

Answer 1

Dilate, Reflect

Not congruent, dilations are used

Explanation:

Dilate Figure K by a factor 3 to get the white shape.

Reflecting the resulting figure over the x-axis will give you Figure L

Step 1: Dilate by a scale factor of 3

Step 2: Reflect over the x-axis

Since dilations are used, the shapes are not congruent as they change the side lengths and area.
