Question

plz plz plz plz tell me answer​

Answer 1

Given :  QR = 6.3 cm ∠Q =75°

PQ + PR = 9 cm

To Find :  Construct triangle PQR

Solution:

Step 1 : Draw a line segment QR = 6.3 cm

Step 2 : Draw an angle of 75° at Q on QR

Step 3 : take a length of  9 cm from Q and cut angle drawn at  S.

Step 4 : Join RS

Step 5 : Draw perpendicular biscetor of RS intersceting QS at P

Step 6 : Join PR

Required triangle is constructed

Justification

as MP is perpendicular bisector of RS

=>  PS = PR

QS = 9 cm = PQ + PS

=> 9 cm  = PQ + PR
