VWXYZ - 5 intersecting Rectangular planes
Five intersecting rectangular planes. Great for beginners! Assembly is easier than 3 intersecting planes, don't have to squeeze the units.
Before starting 6 intersecting planes given in the book Ornamental Origami: Exploring 3D Geometric Designs I wanted to try this one. Just to get some extra confidence!!
Number of units: 5 x 4 units. 5 planes 4 units in each.
Difficulty: easy to make units and easy to assemble.
Paper size : Printer paper , I think I took 6 cm x 12 cm. Paper size should be in 1:2 ratio
Time: Can be finished in 3 hours
Base angle = 360/4 = 90 degrees.
Notice that the angle obtained when we fold the unit is 45 degrees. (If we take a single unit, there's 90 degrees and when we fold that, we are actually obtaining angular bisector, so after the fold the angle we have is 45 degrees )
When we join two units, the angle is 45 + 45 = 90 degrees which is clearly evident from the figure.
Assembly: Connect 5 units of different colors and go on joining keeping pieces of same color in one plane.
