Introduce Prism
Prism
Definition of Prism
· A prism is a polyhedron consisting of two parallel, congruent faces called bases.
More about Prism
· A prism is named by the shape of its base.
· Triangular Prism: A Prism with triangular bases is a Triangular Prism.
· Rectangular Prism: A Prism with rectangular bases is a Rectangular Prism.
· Cube: A prism with square bases is a cube. All six faces of a cube are squares.
· Pentagonal Prism: A Prism with pentagonal bases is a Pentagonal Prism.
· Hexagonal Prism: A Prism with hexagonal bases is a Hexagonal Prism.
· Octagonal Prism: A Prism with octagonal bases is an Octagonal Prism.
Examples of Prism
Introducing 2-D and 3-D Shapes
SHAPE
A shape is a geometric figure that can be described with mathematics. One way to classify shapes is to describe a bigger shape that the shape fits inside of. For example, two-dimensional shapes like circles will fit inside of a flat plane. Three-dimensional objects like cubes will not fit inside of a plane, because they are not flat.
Two shapes are said to be equal, if one can be changed into the other by spinning, moving, growing bigger, shrinking, or more than one of these in a combination.
2D shape
· circles
· squares
· triangles
· ovals
· kites
· rectangles
These are two-dimensional shapes or flat plane geometry shapes. Their sides are made of straight or curved lines. They can have any number of sides. Plane figures made of lines are called polygons. Triangles and squares are examples of polygons.
3D shapes
§ spheres
§ cubes
§ cones
§ pyramids
§ hemispheres
§ cuboids
§ cylinders
These are three-dimensional shapes. Their sides are made of flat or curved surfaces.
