Front

The triangles are similar, solve for the question mark: ? = 18.

Back

The value of the question mark is 18.

Front

What similarity shortcut would prove that these triangles are similar?

Back

AA∼ (Angle-Angle similarity).

Front

Define similar triangles.

Back

Triangles that have the same shape but may differ in size; their corresponding angles are equal and corresponding sides are proportional.

Front

What is the AA similarity criterion?

Back

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

Front

What does the SSS similarity criterion state?

Back

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

Front

What is the SAS similarity criterion?

Back

If two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

How do you find the scale factor of similar triangles?

Back

Divide the lengths of corresponding sides of the triangles.
