Triangle Descriptions

What are congruent triangles?

• Triangles that have the same side lengths but different angles.

• Triangles that have the same shape but different sizes.

• Triangles that have the same shape and size.

• Triangles that have the same angles but different side lengths.

How can you prove that two triangles are congruent?

• By measuring the angles of the triangles and comparing them.

• By measuring the lengths of the sides of the triangles and comparing them.

• Using congruence criteria such as SSS, SAS, ASA, AAS, or HL.

• By comparing the areas of the triangles.

What are the criteria for triangle congruence?

• Side-Side-Angle (SSA)

• Angle-Angle-Angle (AAA)

• The criteria for triangle congruence are Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), and Angle-Angle-Side (AAS).

• Side-Side-Side-Angle (SSSA)

If two triangles are congruent, what can you say about their corresponding sides and angles?

• Their corresponding sides and angles are not equal.

• Their corresponding angles are equal but sides are not.

• Their corresponding sides are equal but angles are not.

• ≈

What are similar triangles?

• Triangles that have the same size but not necessarily the same shape.

• Triangles that have different shapes and sizes.

• Triangles that have the same shape but not necessarily the same size.

• Triangles that have the same shape and size.

How can you prove that two triangles are similar?
