Question

Write steps that how to construct triangle KLM, if its perimeter is 10.5 cm and angle L = 120 degrees and Angle M = 30 degrees.

Answer 1

draw a line PQ of 10.5 cm
draw 120° at p and at q 30°
draw angle bisector of p and q which intersect at k
draw perpendicular bisector of pk and qk which intersect PQ at L and m
join KL and km
