5th Period Fast and Curious: Similar Figures

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is AA Similarity?

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 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

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

Back

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

Front

What does it mean if two figures are not similar?

Back

If two figures are not similar, it means that their corresponding angles are not equal or their corresponding sides are not in proportion.
