Question

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

Answer 1

Draw perpendiculars PE, QH, RI and SK from P, Q, C,R and S on the x-axis. Also, draw perpendiculars PF, QG, RJ and SL on the y-axis.

From the figure, we have:

PF = 10 cm and PE = 70 cm

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

Similarly, QG = 12 cm and QH = 80 cm

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

RJ = 16 cm and RI = 100 cm

So, the coordinates of vertex R are (4, 6).

SL = 20 cm and SK = 120 cm

So, the coordinates of vertex S are (5, 3).
