Construct a triangle ABC, in which ∠B = 60°, ∠C = 45° and AB + BC + CA = 11 cm Steps of Construction: 1.Draw a line segment PQ equal to AB  + BC + CA = 11 cm. Make ∠ LPQ = ∠B = 60° and ∠ MQP= ∠C = 45° Bisect ∠ LPQ and ∠ MQP. Let these bisectors intersect at a point A . Draw perpendicular bisectors of line AP and AQ Let XY intersect PQ at B and RS intersect PQ at C. Join AB and AC Thus, Δ ABC is a the required triangle
