Dilation- Geometry Dilations

What is a dilation?

• An enlargement or reduction also known as a stretch or a shrink

• A horizontal shift

• A vertical shift

• A reflection

When the scale factor is greater than 1 the figure gets

• bigger-ENLARGEMENT

• smaller-REDUCTION

A scale factor bigger than 0 but less than 1 makes the figure

• bigger-ENLARGEMENT 

• smaller-REDUCTION

The coordinate for O' will be

• (-4,1)

• (-8,2)

• (8,2)

• (-2,3)

The coordinate for G' will be

• (2,-2)

• (4,-4)

Will this be an example of an enlargement or a reduction?

• Enlargement

• Reduction

The new coordinate for A' will be

• (3,3)

• (9,9)

• (1,1)

True or false: Dilations change the size of the shape

• True

• False
