Probability is that branch of Mathematics which deals with the measure of uncertainty in various phenomenon that gives several results or outcomes instead of a particular one.
Statistics is a branch of Mathematics which deals with collection, presentation, analysis, interpretation of data and drawing of inferences or conclusions there from.
Trigonometry is that branch of Mathematics which deals with the measurement of the sides and the angles of a triangle and the problems related to angles. Ratios of the sides of a triangle with respect to its acute angles are called trigonometric ratios.
Solid figures include cube, cuboid, cylinder, cone, sphere, and hemisphere.
Plane figures include triangle, circle, square, rectangle, and parallelogram.
A circle is a collection of all points which are at a constant distance from a fixed point. The fixed point is called the centre of the circle. A line segment joining centre of the circle to a point on the circle is called radius of the circle.
Quadrilateral is a plane, closed, geometric figure with four sides. A quadrilateral has four sides - AB, BC, CD and DA, four angles - ∠A, ∠B, ∠C, ∠D, two diagonals - AC and BD, and four vertices - A, B, C and D.
The angles opposite to equal sides of a triangle are equal. The sides opposite to equal angles of a triangle are equal.
Two lines can either be parallel or intersecting. Three lines may be parallel to each other, intersect each other in exactly one point, intersect each other in two points (transversal), or intersect each other at most in three points.
Triangles is a a plane figure bounded by three line segments. The sum of the three interior angles of a triangle is 180º.
Line Segment is the portion of the line between two points A and B. A line segment has two end points. Ray is a line segment AB when extended in one direction.
Sequence or progression is a group of numbers forming a pattern. Arithmetic Progression (AP) is a progression in which each term, except the first, is obtained by adding a constant to the previous term.
Linear polynomial is a polynomial having degree 1. Equation means two expressions separated by sign of equality. Thus, linear equation involves only linear polynomials - An equation in which the highest power of the variable is 1.
Algebraic expressions are a combination of constants and variables, connected by any or all of the four fundamental operations (+, -, ×, ÷).
Natural Numbers (N) are Counting numbers - 1, 2, 3, 4, and so on. The smallest natural number is 1. Whole Numbers (W) are Natural numbers including 0 - 0, 1, 2, 3, 4 , and son on. The smallest whole number is 0.
India is a Federation having governments at two levels - State level and Union or Central level. The three branches of government - executive, legislature and judiciary exist and function at both the levels.
Local Government is a government of the local people. Being located nearest to the local people, local government institutions are under constant observation of the society.
