Question

Triangles J K L and M N R are shown.
In the diagram, KL ≅ NR and JL ≅ MR. What additional information is needed to show ΔJKL ≅ ΔMNR by SAS?

∠J ≅ ∠M
∠L ≅ ∠R
∠K ≅ ∠N
∠R ≅ ∠K

Answer 1

∠L ≅ ∠R

Reason: JL and KL meet at L, and MR and NR meet at R; the included angles must be congruent for SAS.
