Egyptian Triangle By Paper Folding

When the vertices of a square are joined to the midpoints of the nonadjacent sides -- eight segments in all, a starry shape is formed in which one may discern the famous 3:4:5 triangle, known as the Egyptian or the rope stretchers triangle. How many other similar triangles are there? credits: http://www.cut-the-knot.org/pythagoras/PaperFolding/345Triangle.shtml https://pa3.wikispaces.com/file/view/PythagorasActivity2.pdf
