Example 1

Construct a triangle ABC, in which ∠B = 60°, ∠C = 45° and AB + BC + CA = 11 cm

Steps of Construction:

  1. 1.Draw a line segment PQ equal to AB  + BC + CA = 11 cm.
  2. Make ∠ LPQ = ∠B = 60° and ∠ MQP= ∠C = 45°
  3. Bisect ∠ LPQ and ∠ MQP. Let these bisectors intersect at a point A .
  4. Draw perpendicular bisectors of line AP and AQ
  5. Let XY intersect PQ at B and RS intersect PQ at C.
  6. Join AB and AC

Thus, Δ ABC is a the required triangle
