Front

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

Back

Proportional.

Front

Which triangles are similar to triangle A?

Back

Triangle B.

Front

Are these two triangles similar? Which similarity criterion do you use to prove it?

Back

Yes, SAS Similarity Theorem.

Front

Are these two triangles similar?

Back

No.

Front

What is the AA Similarity Theorem?

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 Theorem?

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 Theorem?

Back

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

Front

What is a dilation in geometry?

Back

A transformation that alters the size of a figure but not its shape.

Front

How do you determine if two triangles are similar using proportions?

Back

Check if the ratios of the lengths of corresponding sides are equal.
