Similar Figures + Vocabulary

Front

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. Their corresponding angles are equal, and their corresponding sides are proportional.

How do you find the missing side of similar figures?

Back

To find the missing side of similar figures, set up a proportion using the lengths of the corresponding sides of the figures.

Front

What is the symbol used to denote similarity between two figures?

Back

The symbol '~' is used to denote that two figures are similar.

Front

What is the relationship between the corresponding sides of similar figures?

Back

The corresponding sides of similar figures are proportional.

Front

How can you determine if two figures are similar?

Back

To determine if two figures are similar, check if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the first step in solving a problem involving similar figures?

Back

The first step is to identify the corresponding sides and angles of the figures.

Front

What does the term 'corresponding sides' refer to?

Back

Corresponding sides refer to sides in two or more figures that are in the same relative position.

Front

What is the significance of the scale factor in similar figures?

Back

The scale factor is the ratio of the lengths of corresponding sides of similar figures, indicating how much one figure is enlarged or reduced compared to the other.
