Question

Which angle is an adjacent interior angle to ∠JKM? ∠JKL ∠MKL ∠KLM ∠LMK

Answer 1

Two angles are adjacent when they have a common side and a common vertex

<JKM and <MKL have a common side MK and a common vertex K

Answer is ∠MKL

Answer 2

∠MKL

Explanation:

Two angles are said to be adjacent angles if they share a common vertex and a common side but they do not overlap.

The triangle given here is ΔMKL with a line extended outside from K to J.

The two angles ∠MKL and ∠MKJ are adjacent angles as they share a common vertex K and a common side which is MK. The angle ∠MKL comes in the closed triangle while ∠MKJ is formed by extending the point K.

Therefore, ∠MKL is an interior adjacent angle while ∠MKJ is the exterior adjacent angle here.
