Question
Find the coordinates of points P, Q, R and S in Fig. 27.8.
Advertisements
Solution
Draw perpendiculars PA, QB, RC and SD from vertices P, Q, R and S on the x-axis. Also ,draw perpendiculars
PE, QF, RG and SH on the y-axis from these points.
PE = 10 units and PA = 70 units
Therefore, the coordinates of vertex P are (10, 70).
QF = 12 units and QB = 80 units
Therefore, the coordinates of vertex Q are (12, 80).
RG = 16 units and RC = 100 units
Therefore, the coordinates of vertex R are (16, 100).
SH = 20 units and SD = 120 units
Therefore, the coordinates of vertex S are (20, 120).
