CBSE Notes for Understanding Quadrilaterals Class 8 Extra Questions

This is the combination of two Latin words; Quardi + Latus. Quadri . means four and Latus means side.So, a polygon that has four sides is known as a quadrilateral. In a quadrilateral, sides are straight lines and are two dimensional. Square, rectangle, rhombus, parallelogram, etc. are the examples of quadrilateral.Formula for angle sum of a polygon = (n – 2) × 180°.Where ‘n’ is the number of sidesExample:A triangle has three sides,Thus, Angle sum of a triangle = (3 – 2) × 180° = 1 × 180° = 180° .

CBSE Notes for Linear Equations in One Variable Class 8 Extra Questions

• Rules for solving a linear equation in one variable:
  • Add the same number on both the sides of the equation.
  • Subtract the same number from both the sides the equation.
  • Multiply both the sides of the equation by the same number.
  • Divide both the sides of the equation by the same non zero number.
  • Transpose a term from LHS to RHS or vice-versa.
• Transposing means taking a term from one side to the other side of an equation while changing its sign.
• The highest power of a linear equation is always one.
• An equation may have linear expressions on both sides of the equation.
• Such equations help us to solve various problems based on numbers, age, perimeters, combination of coins etc. Please refer Linear Equations in One Variable Class 8 Extra Questions for more information.

CBSE Notes for Rational Numbers Class 8 Extra Questions

 Rational Number– Any Number that can be expressed in the form p/q, where p and q are integers and q ≠ 0, is known as rational number. The collection or group of rational numbers is denoted by Q.

Properties of a Rational Number:
Closure- Rational numbers are closed under addition, subtraction and multiplication. For eg.- If p and q are any two rational numbers, then and the sum, difference, and product of these rational numbers is also a rational number. This is known as the closure law.
