what are all lesson in geometry?all the lesson in geometry

To have an idea about what geometry means, you'll have to
cover the following curriculum:

First you need to know what
are the tools of geometry.

Then you'll have to deal with
the relative position of the lines (parallel or
perpendicular)

Then you'll have to be aware what an area of
a geometric shape means and what a perimeter means.

The
next step would be the acquaintance with the most common geometric shape: triangle. Then
you'll have to find out the relations between the elements of the triangle (angles and
sides), relations that lead to similarity or congruence of the triangles. You'll have to
discover what does it mean a right angle triangles, an isosceles or equilateral
triangle.

You'll learn about the other geometric
shapes: quadrilaterals and circles.

You also have to learn
about the coordinate plane.

Once you're becoming aquinted
with the plane geometry, you can move to another level, namely three dimensional shapes
and their extensions.

A special chapter in geometry is the
one concerning vectors. This chapter is very useful in other fields of science you'
studying, such as physics.

The topics described
above would be enough, for the moment, to give a very good idea about this field called
geometry.
