1.	In the given figure \(\overrightarrow {PQ}\) is a straight line. Check whether x and y are vertically opposite angles or not. Give reason.
Answer» \(\overrightarrow {PQ}\) is a straight line. But \(\overrightarrow {SR}\) is not a straight line. If \(\overrightarrow {PQ}\) and \(\overrightarrow {SR}\) are intersecting lines the x and y become vertically opposite angles. So, x and y are not vertically opposite angles.

Answer»

\(\overrightarrow {PQ}\) is a straight line. But \(\overrightarrow {SR}\) is not a straight line.

If \(\overrightarrow {PQ}\) and \(\overrightarrow {SR}\) are intersecting lines the x and y become vertically opposite angles.

So, x and y are not vertically opposite angles.
