Intuitive Geometry is a simple method of drawing anything using basic geometric shapes & patterns- with step by step instructions to draw them yourself using only a pencil, compass and ruler. You do not need any training in art or mathematics to use it and it can be taught to children.
Draw any finite line, find A & B and mark them. Draw a circle with centre A and radius AB & centre B radius AB. Find and join C & D. Draw an arch with centre D and radius DA. Find E, F and G, mark them.
Join E through G to find H, Join F through G to find I. Mark H, I and J. With Radius AB draw two arches, one with centre I and the other with centre H. Join A & I, I & J, J & H and H & B. You have drawn a Pentagon.
Find K & L, mark them. Connect B through K and A through L. Find & mark M. Extend I through M and H through M. You have created 10 divisions.
Draw a circle with centre M and radius MJ. Find and mark N, O, P, Q and R.
Connect N O P Q R to form the second pentagon.
Find & Mark S, T, U, V, W, X, Y , Z, Aa, Bb. You have created 20 divisions. Extend the lines to the circumference of the circle & connect the new pentagons: S U W Y Aa & T V X Z Bb.
Find the new intersections Cc, Dd etc. and connect them through centre M to create a total of 40 divisions. You can continue with this method to create 80, 160, 320 etc. divisions.
Draw any finite straight line AB. Draw a circle of any size on the line. Using the same radius mark 6 divisions on the circumference of the circle. Connect the divisions through the middle to create CF and DE. Using the same radius find and circle G, H, I, J, K, L, M, N, O, P, Q and R.
Connect R & I, R & J, R & M and R & N. Repeat this pattern of connection for points G, I, L, N and P: GP, GK, GL, etc. Find S & T, mark them and find the others. Thicken the rest of the lines to show the dodecahedron.
The Pentagon Net
Draw a line from K through A. Using Radius A1 find 2. Using radius AK draw a circle with centre 2. Create a pentagon using method 2. Repeat the process all around to create the 5 pentagons that form at the base of the original one.
