SOLID GEOMETRY CONTINUES....

Next what we are going to see is Prism.

PRISM:

A prism is a solid object with identical ends, flat faces and the same cross section all along its length. Here cross section is nothing but a straight line cut across the object.

This cross section which is formed looks like a triangle. So it is known as triangular prism.

As it comes under the polyhedron, it has only flat surfaces and no curves. The parts of the prism were

• Bases ( the ends of the prism were parallel and they are bases )
• Sides ( the side faces of a prism were parallelograms and it has the property of a parallelogram)

There are six types of prism. They are

• Square prism i.e cube.
• cuboid i.e rectangular prism.
• Triangular prism.
• Pentagonal prism.
• Hexagonal prism
• Oblique Prism.

.

Again the prism are divided into two types based on their cross section. They are

• Regular prism
• Irregular prism

Whatever we have discussed above is all the examples of regular prism because they have regular cross-section and the cross-section are irregular in irregular prisms.

The next topic is nothing but Pyramids. We will see in later classes.
