In the process of construction of 45∘, which angle would be constructed first?
45° is half of 90°. Hence by bisecting 90°, an angle of 45° can be constructed. Thus, the 90° angle will be constructed first.
Construct with rulerand compasses, angles of following measures:
(a) 60° (b) 30° (c) 90°
(d) 120° (e) 45° (f) 135°
