Unit 5 - Lesson 3 - Similar Polygons

Front

What are similar polygons?

Back

Polygons that have the same shape but not necessarily the same size. Their corresponding angles are equal, and the lengths of their corresponding sides are proportional.

Front

How do you determine if two polygons are similar?

Back

Two polygons are similar if their corresponding angles are equal and the ratios of the lengths of their corresponding sides are equal.

Front

What is the similarity ratio?

Back

The ratio of the lengths of corresponding sides of two similar polygons.

Front

If two polygons are similar, what can be said about their corresponding angles?

Back

Their corresponding angles are equal.

Front

If the lengths of two corresponding sides of similar polygons are 4 cm and 8 cm, what is the similarity ratio?

Back

The similarity ratio is 1:2.

Front

What is the formula to find a missing side in similar polygons?

Back

Front

If polygon ABCD is similar to polygon EFGH, what can be said about the ratios of their sides?

Back

Front

What does it mean if two polygons are not similar?

Back

It means that their corresponding angles are not equal or the ratios of their corresponding sides are not equal.

Front

How can you show that two polygons are similar using proportions?

Back

By setting up ratios of corresponding sides and showing that they are equal.
