HL stands for Hypotenuse-Leg, a criterion for proving the congruence of right triangles.

SAS stands for Side-Angle-Side, which states that 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.

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

ASA stands for Angle-Side-Angle, which 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 triangles are congruent.

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

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

In SAS, the included angle is the angle formed between the two sides being compared, which is crucial for establishing congruence.

No, two triangles cannot be proven congruent with only two sides unless the included angle is also known (SAS criterion).

ASA requires the angle between the two sides to be known, while AAS allows for one side to be non-included.
