1. Identifying 3-D Figures Lesson 12 – 7

2. Vocabulary Three Dimensional (3 – D) Figure: Shapes that have a length, width, and depth/height Face – a flat surface on a 3-D figure. Edge – the segments formed by intersecting faces. Vertex (vertices) – corner of a figure Lateral face – the sides of a 3-D figure Base – top or bottom shape of a 3-D figure. A base is also a face.

3. Vocabulary Prism – has 2 bases, and lateral faces made of rectangles. Pyramid – has at least 3 lateral faces, which are triangles, and only 1 base. Cone – has 1 circular base, and 1 vertex Cylinder – has 2 circular bases, and no vertices Sphere – has no faces, bases, edges, or vertices. A solid figure that has the same distance to any point from the center.

4. Naming the Prism or Pyramid Prisms & Pyramids have 2 names!!!! Prism: identify the base (the shape that can be stacked on each other to form the prism) ‘name of the base’ prism Pyramid – identify the base (the shape that is on the opposite side to the vertex) ‘name of the base’ pyramid

5. Drawing 3-D Figures Lesson 12 – 8

6. 3 Views Top View – what would the shape look like if you only looked from the top. Side View – what would the shape look like if you only looked from the side. Front View – what would the shape look like if you only looked from the front.
