Question

1.) Construct AABC such that ZB =110°, BC = 7.4 cm,
ZC = 70° and construct its incircle.​

Answer 1

Answer:

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
