How to make a Tetrahedron Platonic Solid or a Four Sided D&D die (dice)

Step 2 Make the Base Triangle

1. Turn the paper in a Landscape position.

2. Measure and mark 8mm and 4mm from the left side on the top and bottom of the paper.

3.Connect the marks at top and bottom lightly.

4.Using the ruler measure 8mm from the left hand corner on an angle until it touches the 4mm mark.

5.Repeat the process from the other side. The marks should come to a point and make a perfect 8mm isosceles triangle

6.Double check the measurements and make sure all 3 sides are exactly 8mm.

7.Carefully cut the triangle out.

Marking the lines on the top and bottom of the paper insures you get a nice straight line. The 8mm line is used to find the right edge of the triangle. The 4mm line is used to determine the top of the triangle.
