Five examples of practical exercises from the document
1) Verification of (a+b)2 = a2 + 2ab + b2
Objective: To verify the algebraic identity (a+b)² = a² + 2ab + b² using geometric representation.
Materials Required: Graph paper, ruler, pencil, colored pens.
Procedure: Take a = 3 cm, b = 2 cm. Draw a square of side (a+b) = 5 cm. Divide it into four parts: two squares (a², b²) and two rectangles (ab each). Calculate areas: (a+b)² = 5² = 25 cm²; a² = 3² = 9 cm², b² = 2² = 4 cm², 2ab = 2×3×2 = 12 cm². Verify total area.
Observations: Total area = 25 cm²; a² + 2ab + b² = 9 + 12 + 4 = 25 cm². Identity verified.
Conclusion: The geometric method confirms the algebraic identity (a+b)² = a² + 2ab + b².
Diagram: Square of side 5 cm divided into a² (9 cm²), b² (4 cm²), and two ab rectangles (6 cm² each).
2.) The HCF for two numbers through the division method
Objective: To find the Highest Common Factor (HCF) of two numbers using the division method.
Materials Required: Notebook, pen, calculator (optional).
Procedure: Choose two numbers, e.g., 48 and 18. Divide 48 by 18, record the quotient and the remainder. Divide 18 by remainder. Repeat until the remainder is 0. The last non-zero divisor is the HCF.
Observations: 48 ÷ 18 = 2 (remainder 12); 18 ÷ 12 = 1 (remainder 6); 12 ÷ 6 = 2 (remainder 0). HCF = 6.
Conclusion: The division method accurately determines the HCF, useful for simplifying fractions.
Diagram: Step-by-step division process with numbers 48 and 18.
3.) The sum of angles in the triangle is 180deg
Objective: To verify that the sum of angles in a triangle is 180°.
Materials Required: Protractor, ruler, paper, pencil.
Procedure: Draw a triangle ABC with sides 5 cm, 6 cm, 7 cm. Measure angles ∠A, ∠B, ∠C using a protractor. Sum the angles and verify if they equal 180°.
Observations: ∠A = 60°, ∠B = 70°, ∠C = 50°. Sum = 60 + 70 + 50 = 180°.
Conclusion: The sum of angles in a triangle is always 180°, confirming a fundamental geometric property.
Diagram: Triangle ABC with angles labelled (60°, 70°, 50°).
4.) Pythagoras' theorem
Objective: To verify Pythagoras' theorem in a right-angled triangle.
Materials Required: Graph paper, ruler, pencil.
Procedure: Draw a right-angled triangle with sides 3 cm, 4 cm (legs), and 5 cm (hypotenuse). Construct squares on each side. Calculate areas: 3² = 9 cm², 4² = 16 cm², 5² = 25 cm². Verify if the area of the square on the hypotenuse equals the sum of areas on the legs.
Observations: 9 + 16 = 25 cm², matches 5² = 25 cm². Theorem verified.
Conclusion: Pythagoras' theorem (a² + b² = c²) holds for right-angled triangles.
Diagram: Right triangle with squares on sides (3 cm, 4 cm, 5 cm).
5) The total surface area of the cube
Objective: To find the total surface area of a cube using a physical model.
Materials Required: Cardboard, ruler, scissors, and glue.
Procedure: Construct a cube with a side of 4 cm using cardboard. Calculate total surface area using formula 6a², where a is the side length. Measure each face and verify.
Observations: Side = 4 cm, each face area = 4² = 16 cm², total surface area = 6 × 16 = 96 cm².
Conclusion: The formula 6a² accurately calculates the total surface area of a cube.
Diagram: Cube with side 4 cm, showing six faces.
