The given triangles congruent by SAS congruency . Option D is correct.
What are triangles?
- A 2 dimensional figure bounded by 3 sides is called a triangle.
- Sum of all the angles of the triangle in 180°.
What are congruent triangles?
- Triangles having same shape and size are called congruent triangles.
- There are five types of congruencies, SAS, AAS, SSS, ASA, RHS
What are vertically opposite angles?
The angles opposite each other when two lines cross are called vertically opposite angles.
How to know which of the given statements is true about the triangles?
Considering Δ JKN and Δ LKM
JK = LK (given)
∠JKN = ∠LKM (vertically opposite angles)
KN = KM (given)
So Δ JKN and Δ LKM are congruent by SAS congruency .
