Geometry
Geometry is all about shapes and their properties. The two most common subjects are:
Plane Geometry (is about flat shapes like lines, circles and triangles ... shapes that can be drawn on a piece of paper)



Solid Geometry (is about three dimensional objects like cubes and pyramids).
If you like playing with objects, or like drawing, geometry is for you!
Hint: Try drawing some of the shapes and angles as you learn ... it helps.
Solids !
Solid Geometry is the geometry of three-dimensional space - the kind of space we live in ...

Polyhedra :(they must have flat faces)

Platonic Solids
Prisms
Pyramids




Non-Polyhedra:(if any surface is not flat)
Sphere
Torus
Cylinder
ConeAlso: Volume of a Cuboid
Plane Geometry
Plane Geometry is all about shapes on a flat surface (like on an endless piece of paper).

We devise some easy ways to find whether a particular number is divisible by another number. This is what we call divisibility. some important points regarding divisibility are given below.

1. Any no. is divisible by 2 if the last no. is 0 or 2 or 4 or 6 or 8.

2. Any no. is divisible by 3 if the sum of the digits are divisible by 3.

3. Any no. is divisible by 4 if the last 2 digits are divisible by 4.

4. Any no. is divisible by 5 if the last no. is 0 pr 5.

5. Any no. is divisible by 6 if the no. is divisible by both 2 and 3.
