Question

Construct triangle PQR, angle Q=135°, PQ=QR=4.7 cm. (Use only compass and scale)

Answer 1

to make 135 ° - bisect 120°and 150°

Answer 2

Steps to make it :
Step 1: draw a line PQ of 4.7m
Step 2:draw an arc of 60 Digre then by it draw an arc of 120 digre
Step 3 : then draw an arc of 90 figure from both the points
Step 4 : draw an arc from 90digre ND 120digre we will get the arc of v105digre
Step 5: draw an arc from 105digre ND an arc 120digre we will get the arc of 150digre
Step 6: then at last take an arc from 105digre ND 1 from 150digre we will finally get the arc of 135digre
Then draw the angle of 135digre and then by taking the measure of 4.7cm make the arc on the angle ND then join all the lines
PQR is the required figure
