2. Construct A PQR such that ZP = 70°. ZR = 50°, QR = 7.3 cm. and construct its Incircle​

Answer 1

1) Construct triangle ABC such that angleB =100 Construct triangle ABC such that angleB =100

=Steps of construction:

i. Construct ∆ABC of the given measurement.

ii. Draw the bisectors of ∠B and ∠C. Let these bisectors intersect at point I.

iii. Draw a perpendicular IM on side BC. Point M is the foot of the perpendicular.

iv. With I as centre and IM as radius, draw a circle which touches all the three sides of the triangle
