1 Three-Dimensional Figures

2 Find each missing measure. 1. A = 56 cm 2 2. C = 43.96 ft 3. A = 72 in 2 r 8 cm x cm x in 15 in 6 in

3  Solid: 3D figure that encloses a part of space.  Face: A flat surface or polygon that makes a solid.  Polygon: A closed figure made of three or more line segments.  Bases: A face of a solid usually located on the top or bottom of solid.  Lateral Face: Any side of a solid which is a polygon.  Edge: A line segment where two faces meet.  Vertex: A point where three or more edges meet.

4

5 1. Describe the shape of the solid’s base(s). ◦ 3 sides = Triangular ◦ 4 sides = Quadrilateral: Square, Rectangular or Trapezoid ◦ 5 sides = Pentagonal ◦ 6 sides = Hexagonal ◦ 7 sides = Heptagonal ◦ 8 sides = Octagonal 2. Describe the shape as either a prism or a pyramid.

6 Name the solid that best describes each picture. Triangular Prism Hexagonal Pyramid Cylinder Square Prism Or Rectangular Prism

7 Identify the number of faces, vertices, edges, bases and lateral faces in the hexagonal pyramid.  Bases: 1  Lateral Faces: 6  Edges: 12  Vertices: 7  Faces: 7

8 Identify each of the following. 1. The number of edges on a pentagonal pyramid. 2. The number of vertices on an octagonal prism. 3. The number of bases on a cone. 4. The number of faces on a hexagonal pyramid. 5. The number of faces on a hexagonal prism.

9 How is a prism or pyramid named?

10 Target: Identify the names and qualities of three-dimensional figures.
