Scale Copy Practice

Front

What is a scaled copy?

Back

A scaled copy is a figure that is similar to another figure but is either larger or smaller by a certain scale factor.

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size, and their corresponding angles are equal.

How do you determine the scale factor between two similar figures?

Back

The scale factor is determined by dividing the length of a side of the scaled copy by the length of the corresponding side of the original figure.

If the scale factor is 2, what does that mean?

Back

It means that the sides of the scaled copy are twice as long as the corresponding sides of the original figure.

If HJ corresponds to AB in a scaled copy, what can you say about their lengths?

Back

The length of HJ in the original figure is proportional to the length of AB in the scaled copy.

What is the value of x if the missing side in a scaled copy is given as x = 20?

Back

The value of the missing side is 20.

How can you tell if two figures are scaled copies of each other?

Back

Two figures are scaled copies if their corresponding angles are equal and the lengths of their corresponding sides are in the same ratio.

Front

What does it mean if Figure B is not a scaled copy of Figure A?

Back

It means that Figure B does not maintain the same shape or proportionality in side lengths compared to Figure A.

Front

What is the importance of identifying corresponding sides in scaled copies?

Back

Identifying corresponding sides helps in understanding the relationship between the figures and in solving problems related to their dimensions.
