Dilation Flashcard

Front

What happens to a figure when the scale factor is greater than one?

Back

The figure undergoes an enlargement.

Front

What are the new coordinates of point A' if Triangle ABC is dilated using a scale factor of 1/2 and point A is at (-6, 6)?

Back

(-3, 3)

Front

What are the coordinates of C' if Triangle ABC is dilated by a scale factor of 1/2 and point C is at (6, -3)?

Back

(3, -1.5)

Front

What are the coordinates of the image after dilating the points A(1,3), B(-2,4), C(5,-7) by a scale factor of 3 with the origin as the center of dilation?

Back

A'(3,9) B'(-6,12) C'(15,-21)

Front

If a dilation produces a congruent figure, what is the scale factor?

Back

1

Front

Define dilation in geometry.

Back

Dilation is a transformation that alters the size of a figure but keeps its shape, using a scale factor.

Front

What is the scale factor in a dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced.

Front

If the scale factor is less than one, what happens to the figure?

Back

The figure undergoes a reduction.

Front

How do you find the new coordinates of a point after dilation?

Back

Multiply the original coordinates by the scale factor.

Front

What is the effect of a scale factor of 2 on a figure?

Back

The figure is enlarged to twice its original size.
