Front

What is the measure of angle R if m∠R = 128°?

Back

To find m∠Q, use the fact that the sum of angles in a triangle is 180°. Therefore, m∠Q = 180° - m∠R - m∠other angle.

What is the measure of angle b if the options are 36°, 56°, 63°, 117°?

Back

The measure of angle b is 36°.

Find the value of x if the options are 21, 19, 36, 27.

Back

The value of x is 21.

Front

Determine x if the options are 93, 71, 81, 55.

The value of x is 71.

Front

Write a congruence statement for the triangles ΔDHF and ΔPZR.

Back

ΔDHF ≅ ΔPZR.

Front

Write a congruence statement for the triangles ΔFDH and ΔPRZ.

Back

ΔFDH ≅ ΔPRZ.

Front

Write a congruence statement for the triangles ΔHDF and ΔRZP.

Back

ΔHDF ≅ ΔRZP.

Front

What is the sum of the interior angles of a triangle?

Back

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

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is the Angle-Side-Angle (ASA) congruence postulate?

Back

The ASA 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.
