What does the SAS postulate state about triangle congruence?

Back

The SAS (Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.

What is the measure of the third angle in a triangle if two angles measure 45° and 75°?

Back

60°

Front

What does the SSS postulate state about triangle congruence?

Back

The SSS (Side-Side-Side) postulate states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

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.

Front

If two angles in a triangle are 45° and 75°, what is the measure of the third angle?

Back

60°

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180°.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What is the measure of angle Y if ∆ BSP ≅ ∆ PYB and angle Y corresponds to an angle of 85° in triangle BSP?

Back

85°

Front

Can three line segments of lengths 12 cm, 7 cm, and 5 cm form a triangle?

Back

No, they cannot form a triangle because 12 cm is not less than the sum of 7 cm and 5 cm.

Front

What is the ASA postulate?

Back

The ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the two triangles are congruent.
