Step 1

First draw a line AB of the dimension equal to the side of a polygon i.e., 50mm.

Step 2

Then draw a perpendicular bisector of the line AB and draw it of sufficient length.

Step 3

Draw a perpendicular line BC from B of the length equal to the line AB.

Step 4

Connect the two points A & C by a straight line. i.e., AC

Step 5

Draw an arc by the center B and radius equal to AB between the points A & C.

Step 6

Mark the point 4 at the intersection of line ‘AC with the perpendicular bisector.

Step 7

Mark the point 6 at the intersection of the arc AC with the perpendicular bisector.

Step 8

Find out the midpoint of between the points 4 & 6 mark it as a point 5.

Step 9

Mark points 7 & 8 at the distance equal to 4-5 or 5-6 in sequence.

Step 10

Draw a triangle ABC by connecting the line AC & BC at point 6.

Step 11

Draw circles by taking the points 4,5,6,7,8 as center points and divide the respective circles with the compass measurement equal to the distance of the line AB. i.e., 50mm.

Step 12

Connect the divided points of respective circles in sequence with straight lines to get respective polygons. Like Square, Pentagon, Hexagon, Heptagon and Octagon.

Step 13

Give the dimensions by any one method of dimensions and give the name of the components by leader lines wherever necessary.
