Question

In $\angle ROP,$ the vertex is at:

• A. $R$
• B. $P$
• C. $O$
• D. None of the above

Answer 1

The correct option is C $O$

Here, the angle is written as $\angle ROP$ and the angle is made by the intersection of two lines.

So, here $RO$ and $OP$ are two lines which makes the angle at point $O$.

Hence, the vertex is at $O$.
