What does SAS stand for in triangle congruency?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruency where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

What does AAA stand for in triangle congruency?

Back

AAA stands for Angle-Angle-Angle, which indicates that if two triangles have equal corresponding angles, they are similar but not necessarily congruent.

What does SSA stand for in triangle congruency?

Back

SSA stands for Side-Side-Angle, which is not a valid criterion for triangle congruency as it can lead to ambiguous cases.

If ΔABC ≅ ΔDEF, what can be inferred about their corresponding sides and angles?

Back

If ΔABC ≅ ΔDEF, then the corresponding sides AB = DE, BC = EF, AC = DF and the corresponding angles ∠A = ∠D, ∠B = ∠E, ∠C = ∠F.

How can you determine if two triangles are congruent using the SSS criterion?

Back

The SSS criterion states that if all three sides of one triangle are equal to the three sides of another triangle, then the triangles are congruent.

What is the difference between congruence and similarity in triangles?

Back

Congruence means that two triangles are identical in size and shape, while similarity means that two triangles have the same shape but may differ in size.
