If ∆LMK ≅ ∆LMT, what can we conclude about ∠K?

Back

∠K ≅ ∠T, since corresponding angles in congruent triangles are equal.

Can two triangles be congruent if they only have two sides and a non-included angle equal?

Back

No, two triangles cannot be proven congruent by SSA (Side-Side-Angle) alone.

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.

What is the SSS criterion for triangle congruence?

Back

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