Answer:
Option 2 is correct.
Step-by-step explanation:
Given the figure
we have to identify the angle or side that is common to triangle NPM and triangle OPM.
In ΔNPM and ΔOPM, the side MP is the common base of both the triangles or we can say the triangles NPM and OPM have common base MP.
Hence, the side which is common in both the triangles is side MP.
Therefore, option 2 is correct.
