Construct a triangle ABC, given that BC is 3 cm, = 60˚ and = 45˚.
Using the steps described in constructing a 60˚ angle, we construct = 60˚ and length of BC = 3 cm.
Step 2 :
To get = 45˚, we have to first get a 90˚ angle and then bisect it to 45˚. Using the steps described in Section 1.5, we construct a line perpendicular (90˚) to BC and passing through C. Then, we construct an angle bisector for the right angle to complete the construction of angle ABC.
