Chhattisgarh Board Solutions for Chapter: Circle and its Elements, Exercise 5: EXERCISE 5.4

In the given fig. $\mathrm{O}$ is the centre of a circle whose diameter is $\mathrm{PQ}$ find the measures of $\angle \mathrm{PRQ} \& \angle \mathrm{QPR}$

In the given fig. angles in the segment of the circle $PQXY$  arc $\angle YPQ=70°$ &$\angle YQP=30°$ find out measurement of $\angle PYQ \& \angle PXQ$

In the given figure, $PQ=QR$ and the centre of a circle is $O$, then find the three angles of the triangle $PQR$.

In the given figure, $AB=AC$ and $\angle ACB=65°$ find out the measure of $\angle BDC$ (in degrees).

In the given figure, find out the angle measures for $\angle PTR$ and $\angle PSR$ where $\angle PQR=130°$.
