MCQ
Plot the point P$(3, 4)$ on the graph paper and rotate it through $90^\circ $ in anti - clockwise direction, about the origin. Find the new position of $P$.
- ✓$P′(-3, 4)$
- B$P′(3, -4)$
- C$P′(3, 4)$
- D$P′(-3, -4)$
Point $P$ is lie in$1^{st}$ quadrant.
Now rotate point $P$ through $90°$ in anti - clockwise direction oror rotate coordinate axis through $90°$ in clockwise direction.
After rotation , point $P$ will lie in $2$nd quadrant ,hence coordinate of $P$ will become $(-3, 4).$
