Front

What does AAA stand for in triangle congruence?

Back

AAA stands for Angle-Angle-Angle, which is NOT a valid method for proving triangles are congruent.

Front

What are the valid methods for proving triangles are congruent?

Back

The valid methods are ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), SAS (Side-Angle-Side), and SSS (Side-Side-Side).

Front

Which method is NOT a way to prove triangles are congruent?

Back

SSA (Side-Side-Angle) is NOT a valid method for proving triangle congruence.

Front

If a triangle has sides of lengths 10, 8, and 3, what can be said about it?

Back

It is not a triangle because the sum of the lengths of any two sides must be greater than the length of the third side.

Front

In triangle congruence, what does SAS stand for?

Back

SAS stands for Side-Angle-Side, which is a method to prove triangles are congruent by showing two sides and the included angle are equal.

Front

What must be verified to use the SAS method for triangle congruence?

Back

You must verify that the two sides are congruent and the included angle is congruent.

Front

How do you order angles in a triangle based on side lengths?

Back

The angles are ordered from least to greatest based on the lengths of the opposite sides.

Front

In triangle RQM, if angle R = 40°, angle Q = 60°, and angle M = 80°, what is the order of the sides from least to greatest?

Back

The order of the sides from least to greatest is QM, RM, RQ.

Front

What is the relationship between angles and sides in a triangle?

Back

In a triangle, the larger the angle, the longer the side opposite that angle.

Front

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
