Quiz 01 | Answer Key
Section A: Multiple Choice Questions (2 marks each)
1. B) 180°
Sum of angles in any triangle = 180°
2. B) 50°
Third angle = 180° - 65° - 65° = 50°
3. C) 360°
Sum of angles in any quadrilateral = 360°
4. D) 6
A regular hexagon has 6 lines of symmetry
5. C) 4
A square has rotational symmetry of order 4 (90°, 180°, 270°, 360°)
Section B: Short Answer Questions (3 marks each)
6. 57°
Third angle = 180° - 45° - 78° = 57°
7. 93°
Unknown angle = 360° - 85° - 110° - 72° = 93°
8. 115°, 65°, 115°
Opposite angles in a parallelogram are equal Adjacent angles are supplementary (add to 180°) Angles: 65°, 115°, 65°, 115°
9. 6 faces, 12 edges, 8 vertices
A cuboid has 6 faces, 12 edges, and 8 vertices
10. Equilateral triangle
A triangle with all angles equal (60° each) is equilateral
Section C: Problem Solving (4 marks each)
11. x = 145°
Angles on a straight line sum to 180° x + 35° = 180° x = 145°
12.
- (a) angle Q = 108°
- (b) angle R = 72°
In a rhombus, opposite angles are equal and adjacent angles are supplementary P = R = 72°, Q = S = 180° - 72° = 108°
13. x = 20°; angles are 40°, 60°, 80°
2x + 3x + 4x = 180° 9x = 180° x = 20° Angle A = 40°, Angle B = 60°, Angle C = 80°
14. 108°
Sum of interior angles = (5-2) × 180° = 540° Each angle = 540° ÷ 5 = 108°
15. 3 lines of symmetry
An equilateral triangle has 3 lines of symmetry, each from a vertex to the midpoint of the opposite side
Section D: Challenging Problems (5 marks each)
16.
- (a) 70°
- (b) 70°
- (c) 20°
(a) & (b): In isosceles triangle with PQ = PR, base angles are equal PQR = PRQ = (180° - 40°) ÷ 2 = 70° (c): In triangle QSR, angle QSR = 90° (perpendicular) angle SQR = 180° - 90° - 70° = 20°
17.
- (a) 95°
- (b) 65°
In a trapezium with AB || DC: Co-interior angles are supplementary angle BCD = 180° - 85° = 95° angle CDA = 180° - 115° = 65°
