Geometry CLASSIFYING SOLIDS

Prisms  Prisms are named for their base shape:  Rectangular Prism  Triangular Prism  Hexagonal Prism  Pentagonal Prism  Octagonal Prism  Trapezoidal Prism  Square Prism

Prisms  Prisms are made up of two bases and rectangular faces connecting the edges of the bases two each other.

Cylinders  Cylinders have a circle for a base and one rectangular face curved around the circumference of the circle

Pyramids  Pyramids are named for their bases as well  Rectangular Pyramid  Triangular Pyramid  Hexagonal Pyramid  Pentagonal Pyramid  Octagonal Pyramid  Square Pyramid

Pyramids  Pyramids are made up of one base and triangles which converge at a point (vertex) opposite the base

Spheres and Hemispheres  Spheres are shaped like a round ball  A hemi-sphere is half a sphere

Cones  Cones have a circle for a base and a curved face that converges at a vertex opposite the base

Geometry SURFACE AREA

Surface Area  The surface area of a shape is defined as the sum of the areas of all the faces

Surface Area of A Cylinder

Surface Area of A Prism  The surface area of a prism is found by finding the area of the bases and adding this value to the areas of the rectangular faces.
