How to construct a -degree angle?
Step 1: First draw a straight line.
Step 2: Then open the compass of the length of the line.
Step 3: Then put the compass on the one end of the line and draw an arc.
Step 4: Similarly put the compass on the midpoint of a line and draw an arc that cuts the first arc.
Step 5: Then join the end of the line and intersecting point of the arcs.
This is the construction of angle.
Hence in this way, we can construct the angle.
