What is the SSS postulate?

Back

SSS stands for Side-Side-Side, a postulate that states if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

What is the SAS postulate?

Back

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

Can triangles be congruent if only the angles are known?

Back

No, triangles cannot be proven congruent solely by knowing the angles (AAA); they must have at least one side length known.

If ΔDEC ≅ ΔBEA, what can be inferred about their corresponding parts?

Back

The corresponding parts of congruent triangles are equal, meaning the angles and sides of ΔDEC are equal to those of ΔBEA.

What is the difference between ASA and AAS?

Back

ASA requires the included side between two angles to be equal, while AAS requires a non-included side to be equal along with two angles.
