How to draw heptagon in engineering drawing

Here's a very complicated construction, yet very accurate.

1. Draw circle O. Draw ABCDE, a pentagon inscribed in circle O.
2. Draw another circle at O, this time inside the pentagon (purple). To do this, find the midpoint of one of the sides of the pentagon and draw a circle crossing that point.

   Accurately construct a heptagon with our simple guideA regular heptagon (also called septagon) is a polygon with seven equal sides and seven equal angles.

6. Use the compass to mark points along the circumference, then connect these points with straight lines to form the heptagon.
7. Draw OA. OA intersects the small circle (purple) at F.
8. Draw a circle at F (cyan) that crosses A. It crosses OA at H. Draw a circle at A (cyan) that crosses H.

   Circle A (cyan) crosses OA at G.

9. Draw a small circle at O (yellow) that crosses H.
   How to draw heptagon easy step by step geometry lesson.

   Inscribe an equilateral triangle, HIJ inside that circle (yellow).

10. Draw a line through points I and J.
11. Draw a circle at O that crosses point G. This circle crosses IJ at points K and L.

    Use the compass to mark points along the circumference, then connect these points with straight lines to form the heptagon.

12. G,K,L are 3 points of the heptagon. Use them to find the rest!
