7th grade Similar Figures

Front

What are corresponding sides?

Back

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

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, and their corresponding angles are equal while the ratios of their corresponding sides are equal.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same relative position in similar figures.

Front

If two triangles have sides in the ratio of 2:3, are they similar?

Back

Yes, if the corresponding angles are equal, the triangles are similar.

Front

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

Back

The ratios of corresponding sides in similar figures are equal.

Front

What is the term for figures that are the same shape and size?

Back

Congruent.

Front

If triangle ABC is similar to triangle DEF, what can we say about their angles?

Back

The corresponding angles of triangle ABC and triangle DEF are equal.

Front

How do you find a missing side in similar figures?

Back

Use the ratios of the corresponding sides to set up a proportion and solve for the missing side.

Front

What is an example of similar figures in real life?

Back

A map and the actual area it represents are similar figures.

Front

If two figures have one pair of equal angles, are they similar?

Back

Not necessarily; you need to check if all corresponding angles are equal and the ratios of corresponding sides are equal.
