There are several kinds of two and three-dimensional shapes that we see around us every day. Some two-dimensional shapes have their extension in three dimensions.

For instance : 3D extension of a circle is a sphere and that of rectangle and square are cuboid and cube respectively. In the same way, we come across with three-dimensional extension of a parallelogram. It is known as "Parallelepiped" which has six parallelogram-shaped faces. In mathematics, a parallelepiped is seen and dealt very commonly.

Addition Rule of Probability

Probability refers to the chance of happening of a particular event. Say for example if we toss a coin, the chance of getting heads is 50%. Thus we say that the probability of heads is 50% or 0.5. In general, the probability of an event is given by the formula

Parallel Lines and Angles Worksheets

If two lines start from two different points, always lie in same plane and also never meet or intersect each other, then these lines are called parallel lines. The distance between two parallel lines at any point are the same throughout their entire length. They have no common point on that plane.

Right triangle is a triangle whose one of the angle is right angle and remaining two angles are equal .It is made up of three sides namely base, perpendicular side and hypotenuse and three angles.

Right Triangle Calculator is used to calculate the perimeter as well as area of the triangle. Observe the figure,here a is the perpendicular side and b is the base and c is the hypotenuse.

Area of a Triangle Worksheet

The total space inside the boundary of the triangle is called as the area of the triangle. Area is measured in terms of square unit.

Area of triangle = 1212 * Base * Height

A rational function is the ratio of two polynomials

A rational function is any functions which can be written as the ratio of two polynomial functions. In the case of one variable, a function is called a rational function if and only if it can be written in the form x=p(x)q(x)x=p(x)q(x) where, P and Q are polynomial functions in x.
