Among the following the true statement is/are

i)Point $\text{'}P\text{'}$ belongs to the angle 

ii)Point $\text{'}A\text{'}$ is in the interior of the angle. 

iii)Point $\text{'}D\text{'}$ is in the exterior of the angle

iv) $\text{'}X\text{'}$ is the common point of $\overrightarrow{OX}$ and $\overrightarrow{OY}$

Any point lying on one of its arms, then that point belongs to that angle. Here $\text{'}P\text{'}$ lies on $\overrightarrow{OX}. \text{'}P\text{'}$belongs to the angle.

The points which are on the same side of initial ray and

co-terminal ray are said to be in the interior of the angle. Hence A is in the interior of the angle.

A point which does not belongs to the angle and which is not in the interior of the angle is called exterior of the angle. Hence $\text{'}D\text{'}$  is in the exterior of the angle.

Common initial point for $\overrightarrow{OX}$and $\overrightarrow{OY}$is called the vertex of the angle. Hence $\text{'}O\text{'}$.$\text{'}X\text{'}$ is not the vertex.

$\therefore$$\left(i\right),\left(ii\right),\left(iii\right)$are true statements
