Scale Review

What is a scaled copy?

• The original picture where the side lengths are different and not being multiplied by the same number

• Just a copy of a figure with different angle measures and different shapes

• A scaled copy is a copy of an figure where every length in the original figure is multiplied by the same number.

What are characteristics of a scaled copy?

• same shape, all angle measures are the same and all side lengths are multiplied by the same scale factor

• same shape and different angle measures

• Has the same exact measurements and placement as the original

• none of the above
