An angle which is greater than $180^{\circ}$ but less than $360^{\circ}$ is called a $\ldots \ldots \ldots .$.

In the figure,sides $QP$ and $RQ$ of $\Delta PQR$ are produced to points $S$ and $T$ respectively. If $\angle SPR = 135^o$ and $\angle PQT = 110^o$,find $\angle PRQ$. (in $^o$)

$A$ part [or portion] of a line with two end points is called a $\ldots \ldots \ldots$

In the figure,lines $AB$ and $CD$ intersect at $O$. If $\angle AOC + \angle BOE = 70^o$ and $\angle BOD = 40^o$,find $\angle BOE$ and reflex $\angle COE$.

An angle whose measure is $90^{\circ}$ is called a $\ldots \ldots \ldots$

In the figure,lines $PQ$ and $RS$ intersect each other at point $O$. If $\angle POR : \angle ROQ = 5 : 7,$ find all the angles.
