A prism is a solid object that has two identical and parallel flat ends called bases, and has the same cross-sectional shape along its entire length. A cross-section is the shape made when cutting straight across an object. Prisms can have different cross-sectional shapes including triangles, rectangles, or other polygons. They are defined as having two identical, parallel bases connected by rectangular or polygonal faces.

1. A PRISM IS A SOLID OBJECT WITH:
Identical ends and
flat faces
and the same cross section all along its length !

2. A CROSS SECTION IS THE SHAPE MADE BY
CUTTING STRAIGHT ACROSS AN OBJECT.
The cross section of this object is a
Triangle. It has the same cross
section all along its length, so it's a
triangular prism.
The cross section of this object
is a rectangle. Each time we cut
it they are still rectangles.

3. Try drawing a shape on a piece of
paper (using straight lines)
Then imagine it extending up from the sheet of paper

4. BASE
Bases
Parallel means: side by side and having the
same distance continuously between them.
The ends of a prism are parallel
and each one is called a base.
These triangles are
side by side. They are
parallel to each other

5. a prism has two faces that are identical
in shape and are parallel. These two faces
are sometimes called the bases of the prism.
Between these two faces are the rest of the
sides of the prism – these sides or faces are
usually rectangles.

6. A cube is a solid figure with
three equal dimensions of
length, width and height.
 It has six square faces.
 This shape has eight
vertices.
 It also has twelve edges
It has 12 edges
It has 6 square faces
It has 8 vertices
(corners)

7. A cuboid is a solid figure with 6
faces which are all rectangles.
 It has six rectangular
faces.
 This shape has eight
vertices.
 It also has twelve edges.

8. TRIANGULAR PRISM
Triangular Prism...
 has 5 faces,
 three faces are rectangular,
 two faces are triangular,
 has 9 edges and 6 vertices.

9. The sides of a pyramid are always triangles. They meet
in a point at the top. This is called the apex. The base is
a polygon, it can be any 2D shape.
PYRIMIDS

10. A cone is like a pyramid but with a circular base instead of a
polygonal base.
 has a curved surface
 has a circuar flat surface
 has an apex
 has two slanted edges
 has a radius and diameter
