Geometry
Geometry is all about shapes and their properties.
If you equal performin with objects, or like drafting, then geometry is for you!
Geometry toilet be divided into:
Plane Geometry is about flat shapes like lines, circles and triangles ... shapes that can be drawn along a piece of paper
Solid Geometry is about three dimensional objects the likes of cubes, prisms, cylinders and spheres.
 | Hint: Try drawing off some of the shapes and angles As you learn ... it helps. |
Channelis, Line, Plane and Solidified
A Point has no dimensions, solely position
A Line of reasoning is one-dimensional
A Plane is cardinal dimensional (2D)
A Solid is three-dimensional (3D)
Why?
Why do we DO Geometry? To discover patterns, notic areas, volumes, lengths and angles, and improved sympathise the world more or less the States.
Plane Geometry
Even Geometry is all around shapes on a flat surface (like on an endless piece of paper).

Satisfying Geometry
Solid Geometry is the geometry of three-multidimensional space - the kind of space we ringing in ...
... let us first with several of the simplest shapes:
Common 3D Shapes
Polyhedra and Non-Polyhedra
There are cardinal main types of solids, "Polyhedra", and "Non-Polyhedra":
Polyhedra (they must have flat faces):
Non-Polyhedra (when whatever surface is non flat):
 | Sphere |  | Torus | |
 | Cylinder |  | Cone |
