Class 9 Maths chapter 9 solutions pdf has a number of questions on area of triangle and area of parallelogram. Practice the solutions as many times as possible to master the chapter!
Area of Triangle:
A triangle has three sides which are joined to each other. A triangle in which of the angle is 90 degrees […]
A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
Characteristics of a Quadrilateral
- A quadrilateral has 4 sides, 4 angles and 4 vertices.
- A quadrilateral can be regular or irregular.
- The sum of all the interior angles of a quadrilateral is 360 degree.
Properties of Parallelogram
There are six important properties of parallelograms to acknowledge:
A triangle has three sides and three angles. The three angles always add to 180 degree. There are three special names given to triangles that tell how many sides (or angles) are equal.
There can be 3, 2 or no equal sides/angles:
- Three equal sides
- Threeequal angles, always 60°
- Two equal sides
- Two equal angles
- No equal sides
- No equal angles
Type of Angle
A line has neither initial nor terminal points with indefinite length.
The pairs of lines are nothing but the two lines, which may be intersects or parallel or perpendicular as shown below:
Euclidean geometry is the study of plane and solid figures on the basis of axioms and theorems employed by the Greek mathematician Euclid. In its rough outline, Euclidean geometry is the plane and solid geometry commonly taught in secondary schools. For details

Linear equations with two variables class 9 covers introduction and methods of solving linear equations with two variables
We all know about linear equation with one variable can be represented as
ax = b where a, b are constants and x is a variable.
Linear Equations with Two Variables will have two variables, it can be represented as
The position of an object on a plane can be defined with the help of coordinate geometry.
What are coordinates?
Consider a plane which is continuous in both the directions. […]
If any given expression has more than three terms, then the expression is called as polynomials.
Types of Polynomials:
The polynomials can be classified based on the number of terms as given below
The polynomial with only one term is monomial
Eg: It’s a number or a number with variable
The polynomial with only two terms is Binomial
Eg: It […]
