SSS,SAS,ASA,AAS Review

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side: A rule stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

Side-Angle-Side: A rule stating that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What does ASA stand for in triangle congruence?

Back

Angle-Side-Angle: A rule stating that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

Angle-Angle-Side: A rule stating that if two angles and a non-included side of one triangle are equal to two angles and a corresponding non-included side of another triangle, the triangles are congruent.

Front

Is Angle-Angle-Angle (AAA) a valid rule for proving triangles congruent?

Back

No, AAA does not prove congruence; it only proves similarity.

Front

If ∠E is 45° and ∠B is 55°, what is the measure of ∠C in triangle ABC?

Back

80° (because the sum of angles in a triangle is 180°).

Front

What is the congruence statement for triangles PRC and prc?

Back

PRC ≅ prc.

Front

If two triangles have two pairs of equal angles, what can be concluded about the triangles?

Back

The triangles are similar, but not necessarily congruent.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect; they are always equal.

Front

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

Back

180°.
