3-Dimensional Figures
• Prisms– Two parallel bases– Named after the
shape of its base– All other faces are
rectangles
Rectangular Prism
Triangular Prism
Hexagonal Prism
3-D figures
• Pyramids– One base– Named after its base– All other faces are triangles
Rectangular Pyramid
Triangular Pyramid
Pentagonal Pyramid
3-D Figures• Cylinder– Two circle bases– Rectangle
wrapped around the circles
Practice
• What is this figure’s name?• How many – Faces?– Vertices?– Edges?
Practice
• What is this figure’s name?• How many – Faces?– Vertices?– Edges?
Practice
• What is this figure’s name?• How many – Faces?– Vertices?– Edges?
Last one…
• What is this figure’s name?• How many – Faces?– Vertices?– Edges?
Come up with a rule…
• For PRISMS:–How many faces, edges, and
vertices it will have– Faces: two plus the number of sides on the base– Vertices: two times the number of sides of the
base– Edges: three times the number of sides of the
base
Draw Me …
• A prism with 15 edges…
Draw me…
• A prism with 8 vertices…
Draw me…
• A prism with 12 faces…
