Construct ΔLMN, in which ∠M =60°, ∠N =80° and LM+MN+NL=11cm.
Given: ∠Q =70°,
∠R = 80° and
perimeter of Δ PQR
Steps of construction:
i: Draw a line segment AB of 11cm.
ii: From point A draw a ray AD at 60° and from B draw a ray BE at 80°
iii: Draw an angle bisector of A and B, two angle bisectors intersect each other at point P.
iv: Draw a line bisector of AP and BP respectively these two-line bisectors intersect at point Q and R
v: Join PQ AND PR
vi: Δ PQR is required triangle.
