How to make the Great Origami Pyramid (page 3)

 

03. Use the protractor to mark two star points of angle 32 degrees from the vertical line.   If you don't have the protractor, you can make use of the formula given:   L = 0.625 * H   If H = 10cm, then L = 6.25cm.   The slop angle of the Great Pyramid is known as 51°51' which is measured at the middle of the pyramid.   We will show you that this slop angle of 51°51' can be translated into 58.3° slop angle at the edge of the pyramid.   And this is the angle (58°) that we are using here.

04. Prepare to apply two valley-folds at two star points.
