Front

What is the image of a figure after a dilation with a scale factor between zero and one?

Back

It has the same shape as the original and is smaller than the original figure.

Front

Image of a square after a dilation with a scale factor of 6?

Back

Its sides are 6 times as long as those of the original square.

Front

What happens to the angles of a triangle after a dilation with a scale factor of 5/6?

Back

Each angle has the same measure as its corresponding angle in the original triangle.

Front

Coordinates of R after dilation by scale factor 1.5 from R(0, -6)

Back

R'(0, -9)

Front

How does the size of an image compare to the original figure when the original figure undergoes a dilation with a scale factor of one?

Back

The figure will remain the same

Front

Algebraic representation of dilation for triangle A'B'C' from triangle ABC: (x, y) --> ?

Back

Front

Which rule best represents the dilation applied to quadrilateral WXYZ to create quadrilateral W’X’Y’Z’? Options: (x, y) --> (0.4x, 0.4y), (x, y) --> (x + 3, y + 2), (x, y) --> (2.5x, 2.5y), (x, y) --> (x - 3, y - 2)

Back
