Question

*Find the coordinates of points P, Q, R and in Fig.**

Answer 1

*Draw perpendiculars PA, QB, RC and SD from vertices P, Q, R and 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

So, the coordinates of vertex P are (10, 70).

QF = 12 units and QB = 80 units

So, the coordinates of vertex Q are (12, 80).

RG = 16 units and RC = 100 units

So, the coordinates of vertex R are (16, 100).

SH = 20 units and SD = 120 units

So, the coordinates of vertex * are (20, 120).
