Question

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.Polygon is shown in the coordinate grid. Match the dilations of to the images showing the result of the dilation.

Answer 1

Looking at the first figure, the coordinates of point D' are the same of point D, and all other points are closer to point D'.

Analyzing the horizontal and vertical distance of all points to point D', the distances decreased by half. That means we have a dilation with center at D by a scale factor of 0.5.

In the second figure, the coordinates of point C' are the same of point C, and all other points are farther from point C'.

Analyzing the horizontal and vertical distance of all points to point C', the distances increased by 50%. That means we have a dilation with center at C by a scale factor of 1.5.

In the third figure, we can see that all distances doubled. The only option with a scale factor of 2 is: center at (6, 3) by a scale factor of 2.

(That means all distances
