Alternate Interior Angle

When two lines are crossed with a line called transversal than the pair of angles formed on the inner but on the opposite side of the transversal are called alternate interior angles. If two lines being crossed are parallel lines than the Alternate interior angles are parallel.

Alternate Exterior Angles

When two lines are crossed with a line called transversal than the pair of angles formed on the outer but on the opposite side of the transversal are called alternate exterior angles. If two lines being crossed are parallel lines than the Alternate exterior angles are parallel.

Eccentricity

Eccentricity can be defined as how much a conic section deviates from being circular. A circle has an eccentricity of 0, this means that eccentricity shows how un-circular a curve is. Higher the eccentricity, lesser the curve. Eccentricity of different curves: A circle has an eccentricity of

Octahedron

An octahedron is a geometrical shape which has 8 faces, twelve edges and six vertices. Examples include boat, heptagonal pyramid, hexagonal prism etc. The 8 faces of the octahedron is triangular in shape. Area of Octahedron If (r) is the distance from the center to one vertex.

Prime Number

A prime number is a whole number which is greater than 1 and is not created by multiplying other whole numbers. Its factors are 1 and the number itself. Numbers which have more than two factors are known as composite numbers. Some of the first prime numbers
