1. What is a point in geometry?

   1. A flat surface
   2. A location with no size
   3. A solid shape
   4. A line with endpoints
   Show answer

   Answer: B. A location with no size

2. Which of the following is a quadrilateral?

   1. Triangle
   2. Square
   3. Circle
   4. Line
   Show answer

   Answer: B. Square

   A quadrilateral is a shape with four sides, and a square is one of the types of quadrilaterals.

3. If the radius of a circle is 7 cm, what is its diameter?

   1. 7 cm
   2. 14 cm
   3. 21 cm
   4. 28 cm
   Show answer

   Answer: B. 14 cm

   The diameter of a circle is twice the radius. Therefore, diameter = 2 * radius = 2 * 7 cm = 14 cm.

4. If a trapezium has bases of length 10 cm and 6 cm and a height of 4 cm, what is its area?

   1. 32 cm²
   2. 40 cm²
   3. 26 cm²
   4. 24 cm²
   Show answer

   Answer: A. 32 cm²

   The area of a trapezium is calculated using the formula: Area = 1/2 * (Base1 + Base2) * Height. Thus, Area = 1/2 * (10 cm + 6 cm) * 4 cm = 32 cm².

5. Calculate the area of a triangle with a base of 8 cm and a height of 5 cm.

   1. 20 cm²
   2. 30 cm²
   3. 40 cm²
   4. 10 cm²
   Show answer

   Answer: A. 20 cm²

   The area of a triangle can be calculated using the formula: Area = 1/2 * Base * Height. Here, Area = 1/2 * 8 cm * 5 cm = 20 cm².
