The triangles shown below may not be congruent.

let's take a peek at the triangles.

they have a 30° angle and a 80° each, and a side that is not in between in common.

[A]ngle [A]ngle [S]ide, AAS congruence.

Option B, False.

Step-by-step explanation:

In the given figure two triangles have been given. In these triangles two angles and corresponding side has been given as equal in measure.

Therefore, by AAS theorem for congruence, the given triangles are congruent.

The given statement that the triangle shown may not be congruent is False.

Option B is the answer.
