  1. A rectangle has a length of 12 inches and a width of 5 inches. What is its perimeter?

    Answer: 34 inches

    Perimeter of a rectangle = 2(length + width) = 2(12 + 5) = 2(17) = 34 inches.

  2. Which of the following best describes a right angle?

    Answer: An angle that measures exactly 90°

    A right angle measures exactly 90° and is often marked with a small square in diagrams.

  3. A circle has a diameter of 10 cm. What is its radius?

    Answer: 5 cm

    The radius is half the diameter, so 10 ÷ 2 = 5 cm.

  4. How many sides does a hexagon have?

    Answer: 6

    A hexagon has 6 sides; the prefix 'hex' means six.

  5. Two angles are supplementary. One angle measures 65°. What is the measure of the other angle?

    Answer: 115°

    Supplementary angles add up to 180°, so 180° − 65° = 115°.

  6. What is the area of a triangle with a base of 8 m and a height of 6 m?

    Answer: 24 m²

    Area of a triangle = ½ × base × height = ½ × 8 × 6 = 24 m².

  7. Which type of triangle has all three sides of different lengths?

    Answer: Scalene

    A scalene triangle has no equal sides, whereas equilateral has three equal and isosceles has two equal.
