THS Similar Triangles AA SSS SAS

Front

What is the AA Similarity Postulate?

Back

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

Front

What does SSS Similarity mean?

Back

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

Front

How can you determine if two triangles are similar using angle measures?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar (AA Similarity).

Front

What is the significance of the similarity statement ΔLMN ∼ ΔPQO?

Back

It indicates that triangle LMN is similar to triangle PQO, meaning their corresponding angles are equal and their corresponding sides are in proportion.

Front

If triangle A is similar to triangle B, what can be said about their corresponding sides?

Back

The lengths of the corresponding sides of similar triangles are in proportion.

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are equal.

Front

Can two triangles be similar if one has a right angle and the other does not?

Back

No, triangles cannot be similar if their corresponding angles are not equal.

Front

What is an example of SSS Similarity?

Back

If triangle ABC has sides 3, 4, 5 and triangle DEF has sides 6, 8, 10, then ΔABC ∼ ΔDEF by SSS similarity.

Front

What does it mean if two triangles are not similar?

Back

It means that their corresponding angles are not equal or their corresponding sides are not in proportion.
