Dilation and Similarity Review

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. This means their corresponding angles are congruent and their corresponding sides are in proportion.

What is AA Similarity?

Back

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

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 congruent, then the triangles are similar.

What is the significance of congruent angles in similar figures?

Back

Congruent angles in similar figures indicate that the figures maintain the same shape, which is essential for establishing similarity.

Can two triangles be similar if they have no congruent angles?

Back

No, two triangles cannot be similar if they have no congruent angles, as angle congruence is a requirement for similarity.

What is the importance of proportional sides in determining triangle similarity?

Back

Proportional sides are important because they ensure that the triangles maintain the same shape, which is a key aspect of similarity.
