# What are the basic formula of plane figures?

Different figures have different formulae; here you will find formulae for the areas of some figures: http://en.wikipedia.org/wiki/Area#Formulae

A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape). The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.

The number of plane figures that can be traced, is that every plane figure can be traced!

Yes, plane figures are flat, not 3-dimensional shapes.

the area and perimeter of the plane figures are square ,rectangle

There are different formulae for different plane figures. Since there are infinitely many possible shapes there are infinitely many formulae.

Plane figures are those that have a length and width but no height. they are two dimensional or flat.

Plane figures are flat (2-dimensional) shapes.

There are infinitely many plane figures, not just five! A circle, ellipse, A triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, and on and on. And then there are mixed figures such as a semicircle, a segment of an ellipse. Not forgetting plane figures that have "random" boundaries.

They are plane figures. Their boundaries are straight lines.The boundaries enclose ONE area.They are plane figures. Their boundaries are straight lines.The boundaries enclose ONE area.They are plane figures. Their boundaries are straight lines.The boundaries enclose ONE area.They are plane figures. Their boundaries are straight lines.The boundaries enclose ONE area.

There is no such formula. To determine the area of an irregular plane shape split it into known shapes such as rectangles, triangles, segments of a circle etc. Determine the area(s) of each of these and sum the results to find the total area.

No. A point has no dimensions whereas plane figures have 2.

A tessellation or tiling of the plane is a collection of plane figures that fills the plane with no overlaps and no gaps.

ones that can be drawn in the plane such as a triangle, circle, etc. A sphere is not one.

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.

Once you know the coordinates, you can use the distance formula to find the lengths of the sides, then using that, you can find the area.

No, take a semicircle, it is a plane figure and is open. Or a parabola is also open and a plane figure.

here are some examples for plane figures: 1) surface of a table 2) notebook 3)wall 4)ground 5)door

No. A square is a plane figure and conventionally for plane figures symmetry is considered in terms of rotation about a point or an axis (in the plane of the figure) but not a plane outside the plane of the square.
