ΔLMN ∼ ΔPQO

Front

If two figures are similar, the corresponding sides are ______________.

Back

proportional

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.

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 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, the triangles are similar.

Front

What is the SSS similarity criterion?

Back

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

Front

How do you determine if two triangles are similar using side lengths?

Back

Calculate the ratios of the corresponding side lengths; if they are equal, the triangles are similar.
