construct a heptagon in a circle of diameter 80mm
To construct a heptagon in a circle of diameter 80mm, follow these steps:
1. Draw a circle with a diameter of 80mm.
2. Find the center of the circle and mark it as point O.
3. Draw a horizontal line through point O, intersecting the circle at two points (A and B).
4. Use a compass to mark a point on the circle (C) that is equal distance from points A and B.
5. Connect points A, B, and C to form an equilateral triangle.
6. Use the compass to find a point (D) on the circle such that the distance from point C to point D is equal to the distance from point C to point A.
7. Connect points C and D to create a line segment.
8. Repeat steps 6 and 7 to find points E, F, G, and H on the circle, creating a total of seven line segments.
9. Connect points D, E, F, G, and H to form the heptagon.
Your heptagon should now be constructed inside the circle of diameter 80mm.
