Properties of a parallelogram ll Cbse NCERT class 9 maths Chapter quadrilaterals

Properties of parallelograms

One special kind of polygons is called a parallelogram. It is a quadrilateral where both pairs of opposite sides are parallel.

There are six important properties of parallelograms to know:

1. Opposite sides are congruent (AB = DC).
2. Opposite angels are congruent (D = B).
3. Consecutive angles are supplementary (A + D = 180°).
4. If one angle is right, then all angles are right.
5. The diagonals of a parallelogram bisect each other.
6. Each diagonal of a parallelogram separates it into two congruent

Practice always makes perfect. In general, to balance an equation, here are the things we need to do: Count the atoms of each element in the reactants and the products. Use coefficients; place them in front of the compounds as needed

Solve Magic square 3x3 amazing maths trick

Magic squares have grown in popularity with the advent of mathematics-based games like Sudoku. A magic square is an arrangement of numbers in a square in such a way that the sum of each row, column, and diagonal is one constant number, the so-called "magic constant." This article will tell you how to solve any type of magic square, whether odd-numbered, singly even-numbered, or doubly-even numbered.

Cross Multiplication- Pair Of Linear Equations In Two Variables

Cross multiplication method for solving linear equation in two variables:

The solution of the equations is given as:

xb1 c2 − b2 c1 = yc1 a2 − c2 a1 = 1b2 a1 − b1 a2 

The condition for consistency of pair of linear equation in two variables must be checked which are as follows:

1.  If a1a2 ≠ b1b2 , then we get a unique solution and the pair of linear equations in two variables are consistent.
2.  If a1a2 = b1b2 = c1c2 , then there exists infinitely many solutions and the pair of lines are coincident and therefore, dependent and consistent.
3.  If a1a2 = b1b2 ≠ c1c2 , then there exists no solution and the pair of linear equations in two variables are said to be inconsistent.
