Class VII Final Exam Maths: Geometry and Fractions

As the exam date approaches, it's essential to focus on the critical areas of mathematics, such as geometry and fractions. This article aims to provide a comprehensive yet concise guide to these subjects, giving you practical tips and key concepts to excel in your final exams.


  1. Lines and Angles

    • Parallel lines: They never intersect and form a constant angle between them.
    • Alternate interior and alternate exterior angles: They are equal in measure.
    • Vertically opposite angles: They are also equal in measure.
  2. Triangles

    • Scalene, isosceles, and equilateral triangles: Based on the properties of their sides.
    • Triangle congruence: Based on the Side-Angle-Side (SAS), Side-Side-Side (SSS), or Angle-Angle-Side (AAS) criteria.
    • Triangle Sum: The sum of all angles of a triangle is 180°.
  3. Circles

    • Radius, diameter, chord, and arc: Key terms related to a circle.
    • Central angle: The angle formed by two radii of a circle.
    • Arc length: The length of a portion of a circle's circumference.
    • Circumference: The total length of a circle's perimeter (2πr).
  4. 3D Geometry

    • Planes, prisms, pyramids, and cylinders: Basic solids in 3D geometry.
    • Surface area and volume: Calculating the area and volume of 3D shapes.
    • Pythagorean Theorem in 3D: The sum of the squares of the lengths of the sides of a right-angled triangle is equal to the square of the length of the hypotenuse (c² = a² + b²).


  1. Simplest Form

    • Divide both the numerator and denominator by their greatest common divisor to simplify a fraction.
    • Examples: 6/12 simplifies to 1/2, and 15/45 simplifies to 1/3.
  2. Adding and Subtracting Fractions

    • Ensure that the fractions have a common denominator before adding or subtracting.
    • Example: 1/4 + 1/6 = (3/12) + (2/12) = 5/12
  3. Multiplying Fractions

    • Multiply the numerators together and multiply the denominators together.
    • Example: (2/3) * (5/6) = (2 * 5) / (3 * 6) = 10/18 = 5/9
  4. Dividing Fractions

    • Multiply the first fraction by the reciprocal of the second fraction.
    • Example: (2/5) / (3/4) = (2 * 4) / (5 * 3) = 8/15
  5. Order of Operations

    • Follow the PEMDAS rule (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) when solving mathematical expressions that involve fractions.

Practice Problems

  1. The perimeter of a triangle is 30 cm. If one angle measures 54°, what are the measures of the other two angles?
  2. What is the area of a circle with a radius of 4 cm?
  3. Simplify the fraction 9/27.
  4. Evaluate the expression (6/7) * (5/8) + (1/3).
  5. If a circle has a circumference of 18.84 cm, what is the length of the chord that is 1/2 of the circumference?

These topics and practice problems will help you prepare effectively for your Class VII final exam in Maths, focusing on geometry and fractions. Remember, practice makes perfect, so take the time to work through these problems and be confident on exam day. Good luck!

Prepare for your Class VII final exam in Maths by reviewing key concepts in geometry and fractions. Learn about lines, angles, triangles, circles, 3D geometry, simplest form of fractions, operations with fractions, and practice problems to test your understanding.
