Dilations Practice (Day 1)

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but not its shape, using a scale factor.

Front

What happens to a figure when the scale factor is greater than 1?

Back

The figure undergoes an enlargement.

Front

What happens to a figure when the scale factor is less than 1?

Back

The figure undergoes a reduction.

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 during a dilation.

Front

If a point (x, y) is dilated by a scale factor of k, what is the new point?

Back

The new point is (kx, ky).

Front

What is the result of dilating the point (2, 3) by a scale factor of 3?

Back

The new point is (6, 9).

Front

What type of transformation is a dilation?

Back

A dilation is a non-rigid transformation.

Front

If triangle ABC is dilated to triangle DEF, what can we say about their angles?

Back

The angles of triangle ABC and triangle DEF are congruent.

Front

If the scale factor is 1, what happens to the figure?

Back

The figure remains unchanged.

Front

What is the difference between a dilation and a reflection?

Back

A dilation changes the size of a figure, while a reflection flips it over a line.
