Unit 4 Flashcard 1 Review: Dilation and Similarity

Front

What does SSS stand for in triangle similarity?

Back

SSS stands for Side-Side-Side similarity, which states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the AA criterion for triangle similarity?

Back

AA stands for Angle-Angle similarity, which states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What does SAS stand for in triangle similarity?

Back

SAS stands for Side-Angle-Side similarity, which 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

If the scale factor is greater than one, what type of transformation occurs?

Back

An enlargement occurs when the scale factor is greater than one.

Front

If the scale factor is less than one, what type of transformation occurs?

Back

A reduction occurs when the scale factor is less than one.

Front

How do you determine corresponding sides in similar triangles?

Back

Corresponding sides in similar triangles are the sides that are in the same relative position in each triangle.

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are equal.

Front

If triangle ABC is similar to triangle DEF, what can be said about their perimeters?

Back

The ratios of the perimeters of similar triangles are equal to the ratios of their corresponding sides.

Front

What is the formula to find the missing side in similar triangles?

Back

The formula is: (side1 / side2) = (missing side / corresponding side).

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, and their corresponding angles are equal.
