Question

Construct a triangle ABC in which B = 60°, _C = 45° and AB + BC+
CA = 11 cm. Also write steps of constructions.​

Answer 1

Answer:

Given : AB+BC+CA=11 cm , ∠B = 60° & ∠C = 45°

To Find : Construct triangle.

Solution: Step 1 : Draw a line segment XY = 11 cm. Step 2 : Make an angle of 60 ° at X on XY using protector. Step 3 : Make an angle of 45° at Y on XY using protector. Step 4 : Draw angle bisector of 60° & 45° and let them intersect at A
