Triangle Similarity Review

Front

What does SAS stand for in triangle similarity?

Back

SAS stands for Side-Angle-Side, a criterion for triangle similarity where two sides of one triangle are proportional to two sides of another triangle, and the included angles are equal.

Front

What does AA stand for in triangle similarity?

Back

AA stands for Angle-Angle, a criterion for triangle similarity where two angles of one triangle are equal to two angles of another triangle.

Front

What does SSS stand for in triangle similarity?

Back

SSS stands for Side-Side-Side, a criterion for triangle similarity where all three sides of one triangle are proportional to the three sides of another triangle.

Front

If two triangles are similar, what can be said about their corresponding angles?

Back

The corresponding angles of similar triangles are equal.

Front

If two triangles are similar, what can be said about their corresponding sides?

Back

The corresponding sides of similar triangles are in proportion.

Front

What is the scale factor in triangle similarity?

Back

The scale factor is the ratio of the lengths of corresponding sides of two similar triangles.

Front

How do you determine if two triangles are similar using the AA criterion?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar by the AA criterion.

Front

What is the relationship between the heights of similar triangles?

Back

The heights of similar triangles are proportional to the lengths of their corresponding sides.

Front

How do you find the height of an object using similar triangles?

Back

You can use the ratio of the heights to the corresponding bases of similar triangles to find the height of an object.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.
