Triangles - Concept Points

Class 9 - Mathematics
Class 9 - Mathematics - Triangles - Concept Points (#eduvictors)(#cbse2020)(#class9Maths)

1. A plane figure bounded by three line segments is called a triangle.

2. A triangle can be:
- equilateral (all three sides are equal)
- isosceles (any two sides are equal)
- scalene (all three sides are unequal)

3. A triangle in which one of the angles measures  90° is called a right-angled triangle or simply a right triangle.

4. The sum of the angles of a triangle is always 180°

5. Two figures are congruent, if they are of same shape and same size. Congruent triangles are exactly identical.

CBSE Class 9 - Maths - Real Numbers - Problems on Rationalisation (Part-5)(#eduvictors)(#class9Maths)(#Class9RealNumbers)

CBSE Class 9 - Maths - Real Numbers - Problems on Rationalisation (Part-5)

CBSE Class 9 - Maths - Real Numbers - Problems on Rationalisation (Part-5)(#eduvictors)(#class9Maths)(#Class9RealNumbers)


The part-5 video gives a solution to a typical problem on rationalisation. This type of problem is commonly asked in question papers. The first step to solve this kind of problem is to rationalise each term individually. The video covers the solution for a long type of answer based question. In this series, we'll try to present solutions for more HOTS and typical problems for students of mathematics of class 9 For study Notes, Worksheets, Question Papers and Assignments for CBSE Class 6 - 12, do check our website www.eduvictors.com

The objective of rationalizing a denominator is to make it easier to understand what the quantity really is by removing irrationals from the denominators. The video series provides solutions for typical problems related to rationalization of irrational numbers covered under chapter real numbers. The video covers the solution for a long type of answer based question.

CBSE Class 9 - Real Numbers - Problem on Rationalisation (Part-3)
CBSE Class 9 - Real Numbers - Problem on Rationalisation (Part-3)(#eduvictors)(#cbseClass9Maths)


The video series provides solutions for typical problems related to rationalization of irrational numbers covered under chapter real numbers. The video covers the solution for a long type of answer based question.

If the denominator of an expression is a surd, it can be reduced to an expression with rational denominator.

If the product of two surds is a rational number, then each one of them is a rationalizing factor of the other.

In this series, we'll try to present solutions for more HOTS and typical problems.

Class 9 - Maths - Real Numbers - Problems on Rationalization -2 For CBSE students (#eduvictors)(#cbseClass9Maths)(#rationalisation)

Class 9 - Maths - Real Numbers - Problems on Rationalization (Part-2) For CBSE students




The video series provides solutions for typical problems related to rationalization of irrational numbers covered under chapter real numbers. The video covers the solution for a long type of answer based question.


If the product of two irrational numbers is a rational number, then each number is called the rationalization factor. The process of multiplying an irrational number by its rationalising factor is called rationalisation. In this series, we'll try to present solutions for more HOTS and typical problems.

CBSE Class 8/9/10 - Mathematics - Typical Factorisation Solved Problems (#class8Maths)(#cbsenotes)(#eduvictors)

Q1: Factorise x⁴ + x² + 1

Answer: x⁴ + x² + 1

= (x⁴ + 2x² + 1) - x²

Using identity (A + B)² = A² + B² + 2AB

= (x² + 1)² - x²

Using identity A² - B² = (A + B)(A - B)

= (x² + 1 + x)(x² + 1 - x) [Answer]
