This shows you can make anything using geometry.  This figure’s basic structure is a circle but is filled with triangles and quadrangles.  There are also lines to carve out the triangles and quadrangles.  There are points that are the vertices of the lines and they are labled.

          All geometric figures have lines and vertices.  These are like the poles supporting the figure.  Angles are also in every geometric figure.  These are the space between the lines coming out from a vertice.  If  a line is coming out exactly to the side, or you can draw a perfect square with 2 lines in the angle, then it is called a right angle or 90 degrees.  If a minute hand on a clock moved 1 minute, then it would move 6 degrees.

         There are basic shapes are triangles, squares or quadrangles, pentagons, hexagons,   heptagons, octagons, nonagons, decagons, dodecagons and other shapes with more sides. These shapes can be turned into 3-D shapes.  A square would be changed to a cube but everything else would be a prism.  For example, a 3-D hexagon is called a hexagonal prism.
