Question

Construct ∆ABC such that m$\angle$A = 55^°, m$\angle$B = 60^°, and l(AB) = 5.9 cm.

Answer 1

Steps of constructions:

(1) Draw seg AB of length 5.9 cm.
(2) Draw ray AD such that ∠BAD = 55°.
(3) Draw ray BE such that ∠ABE = 60°.
(4) Name the point of intersection of ray AD and BE as C.
Therefore, △ABC is the required triangle.
