Unit 6 Vocabulary - Part 2

Front

What does it mean if two triangles are similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the SSS similarity criterion?

Back

The SSS (Side-Side-Side) similarity criterion states that if the three sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar.

Front

What is the SAS similarity criterion?

Back

The SAS (Side-Angle-Side) similarity criterion states that 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

What is the AA similarity criterion?

Back

The AA (Angle-Angle) similarity criterion states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

Front

What is the relationship between the sides of similar triangles?

Back

The lengths of corresponding sides of similar triangles are proportional.

Front

How can you determine if two triangles are similar using angles?

Back

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

Front

What is the significance of congruent angles in triangle similarity?

Back

Congruent angles indicate that the triangles share the same shape, which is a key factor in determining similarity.
