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, either enlarging or reducing it, while maintaining its shape.

Front

What does a scale factor greater than 1 indicate?

Back

A scale factor greater than 1 indicates an enlargement of the figure.

Front

What does a scale factor less than 1 indicate?

Back

A scale factor less than 1 indicates a reduction of the figure.

Front

Back

The shape is reduced to half its original size.

Front

What are similar shapes?

Back

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

Front

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

Back

The scale factor is 2.

Front

What is the scale factor if a shape is reduced to one-third of its size?

Back

Front

If the original length of a side is 10 units and the scale factor is 2, what is the new length?

Back

The new length is 20 units.

Front

If the original area of a shape is 25 square units and the scale factor is 3, what is the new area?

Back

Front

What is the relationship between the scale factor and the dimensions of a figure?

Back

The scale factor determines how much the dimensions of a figure are multiplied to obtain the dimensions of the dilated figure.
