Sample questions

1. What is a quadrilateral?

   1. A three-sided figure
   2. A four-sided figure
   3. A five-sided figure
   4. A six-sided figure
   Show answer

   Answer: B. A four-sided figure

   A quadrilateral is defined as a polygon that has four sides, four vertices, and four angles.

2. What is the sum of the interior angles of a quadrilateral?

   1. 180 degrees
   2. 360 degrees
   3. 540 degrees
   4. 720 degrees
   Show answer

   Answer: B. 360 degrees

   The sum of the interior angles of a quadrilateral can be calculated with the formula (n-2) × 180 degrees, where n is the number of sides. For a quadrilateral, n=4. Thus, (4-2) × 180 = 360 degrees.

3. What is the formula to find the area of a rectangle?

   1. Length + Width
   2. Length x Width
   3. 2(Length + Width)
   4. Length x Height
   Show answer

   Answer: B. Length x Width

   The area of a rectangle is calculated by multiplying the length by the width (A = l × w).

4. A parallelogram has a base of 10 cm and a height of 5 cm. What is its area?

   1. 15 cm²
   2. 25 cm²
   3. 50 cm²
   4. 75 cm²
   Show answer

   Answer: C. 50 cm²

   The area of a parallelogram is calculated using the formula A = base × height. Thus, A = 10 cm × 5 cm = 50 cm².

5. If the diagonals of a rhombus intersect at right angles, what can be said about the lengths of the diagonals?

   1. They are equal.
   2. They are different.
   3. They are perpendicular.
   4. Cannot determine.
   Show answer

   Answer: C. They are perpendicular.

   In a rhombus, the diagonals always bisect each other at right angles, meaning they are perpendicular.
