Scaled Copies Review

Front

What is a scaled copy?

Back

A scaled copy is a shape that is the same shape as the original but different in size.

Front

What does the scale factor represent?

Back

The scale factor is the number you multiply the original shape by in order to get the scaled copy.

Front

If the scale factor is 2, what does that mean for the dimensions of the shape?

Back

It means that each dimension of the original shape is multiplied by 2 to get the dimensions of the scaled copy.

Front

Which of the following is a scaled copy of figure A?

Back

A scaled copy maintains the same shape but can be larger or smaller than the original.

Front

How do you determine the corresponding side lengths in scaled copies?

Back

Corresponding side lengths in scaled copies are proportional based on the scale factor.

Front

If ΔABC has side lengths of 3, 4, and 5, what are the side lengths of a scaled copy with a scale factor of 2?

Back

The side lengths would be 6, 8, and 10.

Front

What is the scale factor from ΔABC to ΔDEF if the side lengths of ΔDEF are 6, 8, and 10?

Back

The scale factor is 2.

Front

If a shape is enlarged by a scale factor of 1/2, what happens to its size?

Back

The shape is reduced to half its original size.

Front

What is the relationship between the original shape and its scaled copy?

Back

The original shape and its scaled copy are similar, meaning they have the same shape but different sizes.

Front

If the original shape has a perimeter of 20 units and the scale factor is 2, what is the perimeter of the scaled copy?

Back

The perimeter of the scaled copy would be 40 units.
