Dilations and Scale Factor B

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but keeps its shape the same.

Front

What does the scale factor indicate in a dilation?

Back

The scale factor indicates how much larger or smaller a figure will be after a dilation.

Front

If the scale factor is greater than 1, what type of transformation is it?

Back

It is an enlargement.

Front

If the scale factor is less than 1, what type of transformation is it?

Back

It is a reduction.

Front

What is the scale factor if a shape is reduced to half its size?

Back

The scale factor is 1/2.

Front

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

Back

Multiply the original coordinates by the scale factor.

Front

What are similar shapes?

Back

Shapes that have the same form but differ in size are called similar.

Front

What is the scale factor if a shape is enlarged to twice its size?

Back

The scale factor is 2.

Front

What mathematical operation is used to apply a scale factor?

Back

Multiplication.

Front

If Point B (3, 4) is dilated by a scale factor of 1/2, what are the new coordinates?

Back

(1.5, 2)
