Given that k ∥ l, identify the congruent angles in the triangles.
∠1≅
∠2≅
∠3≅

The congruent angles in the triangles are,
∠1≅ ∠5
∠2≅ ∠4
∠3≅ ∠6
Two angles are said to be congruent if their corresponding sides and angles are of equal measure.
Two angles are also congruent if they coincide when superimposed.
From given figure, It is observed that transversal line m intersects pair of parallel lines l and k.
So that, corresponding angles , alternate angles and vertically opposite angles are equal.
