Sample Questions and Answers for CBSE 9th Class Maths Solutions:
Q1: What is the Pythagoras theorem?
A1: The Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Q2: How do we calculate the area of a triangle?
A2: The area of a triangle can be calculated using the formula: Area = ½ × base × height.
Q3: What are the properties of parallel lines?
A3: Parallel lines are lines that are always the same distance apart and never meet, no matter how far they are extended.
Q4: How can we solve linear equations with one variable?
A4: To solve linear equations with one variable, isolate the variable on one side by performing inverse operations (like addition, subtraction, multiplication, or division).

A14: Probability is the measure of how likely an event is to occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.
Q15: How do we factorize a quadratic expression?
A15: To factorize a quadratic expression, look for two numbers that multiply to give the constant term and add to give the coefficient of the middle term.
Q16: What is the difference between a variable and a constant in algebra?
A16: A variable is a symbol that represents an unknown value, while a constant is a fixed value that does not change.
Q17: How do we calculate the perimeter of a rectangle?
