In the construct an angle of 60∘ given below.
Steps of construction are:
Step1: Draw a ray AB
Step 2 will be
In the construction of 60∘, the first step is to construct a ray AB and the second step is taking A as the centre and any convenient radius, draw an arc intersecting ray AB at a point D. The third step is to draw an arc with the same radius intersecting at "E" with "D" as the centre.
Using a protractor for construction of the angle would not result in the above figure.
