Question 1: What is the perimeter of a square with a side length of 9 cm?
- 27 cm
- 36 cm (Correct answer)
- 45 cm
- 81 cm
Correct answer: 36 cm
Perimeter of a square = 4 × side = 4 × 9 = 36 cm.
Question 2: What is the area of a triangle with a base of 10 cm and a height of 6 cm?
- 30 cm² (Correct answer)
- 40 cm²
- 60 cm²
- 16 cm²
Correct answer: 30 cm²
Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 cm².
Question 3: How many degrees are in a straight angle?
- 45°
- 90°
- 180° (Correct answer)
- 360°
Correct answer: 180°
A straight angle forms a straight line and measures exactly 180°.
Question 4: Which type of triangle has all three sides of equal length?
- Scalene
- Isosceles
- Right
- Equilateral (Correct answer)
Correct answer: Equilateral
An equilateral triangle has three equal sides and three equal angles of 60° each.
Question 5: What is the volume of a rectangular prism with length 5 cm, width 4 cm, and height 3 cm?
- 36 cm³
- 48 cm³
- 60 cm³ (Correct answer)
- 72 cm³
Correct answer: 60 cm³
Volume = length × width × height = 5 × 4 × 3 = 60 cm³.
Question 6: Two lines that never intersect and are always the same distance apart are called:
- Perpendicular
- Intersecting
- Parallel (Correct answer)
- Diagonal
