Unit 4 - Similar Triangles Test Review

Front

What is the definition of similar triangles?

Back

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

What is the Angle-Angle (AA) Similarity Postulate?

Back

If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

What is the Side-Side-Side (SSS) Similarity Theorem?

Back

If the corresponding sides of two triangles are in proportion, then the triangles are similar.

What is the Side-Angle-Side (SAS) Similarity Theorem?

Back

If one angle of a triangle is congruent to one angle of another triangle and the sides including these angles are in proportion, then the triangles are similar.

What is a scale factor in dilation?

Back

The scale factor is the ratio of the lengths of two corresponding sides of similar figures. It determines how much the figure is enlarged or reduced.
