DCP2 Triangles Practice

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a theorem used to prove that two triangles are congruent if two angles and a non-included side of one triangle are equal to the corresponding parts of another triangle.

Front

What is the AAS triangle congruence theorem used for?

Back

The AAS triangle congruence theorem is used to determine if two triangles are congruent based on two angles and a non-included side.

Front

What is the measurement of ∠1 if it is given that ∠1 + ∠2 = 180° and ∠2 = 65°?

Back

∠1 = 115°.

Front

If two angles of a triangle are 70° and 40°, what is the measure of the third angle?

Back

The third angle is 70° because the sum of angles in a triangle is 180°.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a theorem used to prove that two triangles are congruent if two sides and the included angle of one triangle are equal to the corresponding parts of another triangle.

Front

How do you solve for x in the equation 2x + 10 = 130?

Back

x = 60.

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

If one angle of a triangle is 85° and another is 78°, what is the measure of the third angle?

Back

The third angle is 17°.

Front

What is the definition of congruent triangles?

Back

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

Front

What does AAA stand for in triangle congruence?

Back

AAA stands for Angle-Angle-Angle, which indicates that if three angles of one triangle are equal to three angles of another triangle, the triangles are similar but not necessarily congruent.
