Question

Construct a ∆ PQR in which QR=7cm, < Q =60 0 , < P = 70 0 . Measure PR.

Answer 1

Take tha values and draw a triangle.

First deaw a 7 cm line QR. Draw 60° at Q point. Since

Draw 50° angle at R point.

You will see the lines intersect.

Then measure PR line and you will find the value of the PR side.

PR = 10 cm.
