7th Period Fast and Curious: Similar Figures

Front

What is a scale factor in dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation. It is the ratio of the lengths of corresponding sides of the original figure to the dilated figure.

Front

What does AA Similarity mean?

Back

AA Similarity (Angle-Angle Similarity) states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is SSS Similarity?

Back

SSS Similarity (Side-Side-Side Similarity) states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is SAS Similarity?

Back

SAS Similarity (Side-Angle-Side Similarity) states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

How do you find the missing side in similar figures?

Back

To find the missing side in similar figures, set up a proportion using the lengths of corresponding sides and solve for the unknown.

Front

Back

This means that the dilated figure is one-third the size of the original figure.

Front

Back

This indicates that the dilated figure is twice the size of the original figure.

Front

What is the relationship between corresponding angles in similar figures?

Back

In similar figures, corresponding angles are equal.

Front

What is the relationship between corresponding sides in similar figures?

Back
