Triangles: Shapes in Math, Science and Nature.
Ross, Catherine Sheldrick
This book examines everything having to do with the triangle. It begins with a basic definition of the triangle and continues with discussions on tetrahedrons, triangular prisms, and pyramid shapes. Some ideas addressed include how triangles are used to measure heights and distances, the importance of triangles to builders, Alexander Graham Bell's tetrahedral kites, making a kaleidoscope, and growing a crystal with eight triangular faces. Other topics include types of triangles, adding up the angles, area of a triangle, triangular numbers, and Pascal's triangle. Activities include a triangle weave, a dissection puzzle, triangle fractals, hexaflexagons, building a cardboard bridge, creating a construction kit for prisms, Platonic solids, tetrahedral puzzlers, toothpick architecture, and making pyramids.
