Question

Construct a triangle ABC in which BC = 8 cm, ∠B = 45° and AB − AC = 3.5 cm.

Answer 1

The below given steps will be followed to draw the required triangle 

step 1: Draw the line segment BC = 8cm and at point B, make an angle of 45 degrees , say angle XBC

step 2: cut the line segment BD = 3.5cm (equal to AB - AC) on ray BX

step 3: join DC and draw the perpendicular bisector PQ of DC

step 4: let is intersect BX at point A. Join AC 

triangle ABC is the required triangle
