Question

Draw a regular Pentagon of sides 30mm​

Answer 1

1. Draw a line segment AB.
2. Draw two circles, 1 and 2, centred at A and B, both with radius AB. The points where they intersect each other are C and D.
3. Connect C and D.
4. Draw circle 3 with centre C and radius AB. Circle 3 intersects circles 1 and 2 in E and F respectively. It also intersects line segment DC in G.
5. Connect E and F with G. Extend these lines far enough so they intersect circles 1 and 2. Call these new intersection points H and I.
6. Draw circles 4 and 5 centred at H and I with radius AB. Name the upper intersection point J.
7. Connect A, B, I, J and H.
8. Trace the pentagon in ink or another colour and erase any construction lines (if needed).
