Geometry - Tetrahedron Construction Complete Review

Today we were on our constructing phase of our tetrahedron task. First what we had to do was make 1 equilateral triangle on a big piece of cardboard. Then we had to cut it out of the piece of cardboard. Then we had to make a net to form our tetrahedron. Once we had made our net on our A3 piece of paper using the cardboard triangle we then cut our net out. After we cut the net out we then started forming our tetrahedron. As you already know above there is my completed 3-D tetrahedron.
