1. Solid Shapes

2. The basics ♥Polygon – 2 space ♥Polyhedron = 3 space ♥Polyhedra or Polyhedrons = plural ♥ A Polyhedron is a closed figure, made up of polygons. ♥Parts of a polyhedron: ♥Faces – these are the polygons ♥Edges – where the polygons intersect & form a line ♥Vertices – “corners” – the point where more than two polygons intersect.

3. edge face = Vertex

4. Regular Polyhedra (remember ‘regular’ means all sides have the same length and all angles have the same measure) A regular Polyhedra is composed of congruent regular polygons as faces AND has the same number of faces meeting at each vertex. Can you think of a regular polyhedron?

5. DRAWING PRACTICE!! ♥Let’s learn how to draw a cube. 1.Draw a square. 2.Draw a congruent square, up and to the right. 3.Connect the vertices Notice 4 pair of parallel lines TADA!!
