Question

Construct Δ PQR with PQ = 4 cm, QR = 7 cm and PR = 8 cm.

Answer 1

For constructing Δ

1.Draw a line from P to Q ( PQ = 4 cm. )using scale.

2.Now keep bow compass at P and extend it till 8 cm. and draw a arc M.

3.Similarly keep bow compass at Q and extend it till 7 cm. and draw a arc N such that its intersect with the M.

4.Give name point of intersection R.

5.By joining point PQ and QR we got ΔPQR.
