ones that can be drawn in the plane such as a triangle, circle, etc. A sphere is not one.
plane figures.
A plane is a two dimensional figure that is a set of line segments or sides all lying inside of a single plane. Some examples of plane figures are a triangle, pentagon, octagon, hexagon and circle.

All three are convex plane figures.
There are different kinds of space figures. The names of these space figures are rectangular prisms, cubes, pyramids, and cylinder.

polygon of more than 4 sides and a triangle.
Different figures have different formulae; here you will find formulae for the areas of some figures: http://en.wikipedia.org/wiki/Area#Formulae
Conic Sections are figures that can be formed by slicing a three dimensional right circular cone with a plane. There are different ways to do this, and each way yields a different figure. These figures can be represented on the graph as well as algebraically. The four conic sections are circles, ellipses, parabolas, and hyperbolas.

The number of plane figures that can be traced, is that every plane figure can be traced!
There are different formulae for different plane figures. Since there are infinitely many possible shapes there are infinitely many formulae.
Yes, plane figures are flat, not 3-dimensional shapes.
the area and perimeter of the plane figures are square ,rectangle
