Sample question 1
The sum of the interior angles of a polygon with n sides is:
- 360°
- (n − 2) × 180°
- n × 180°
- (n − 1) × 180°
Answer: B. Joining one vertex to the others splits the polygon into n − 2 triangles, each with angle sum 180°.
Sample question 2
Why is a rectangle that is not a square not a regular polygon?
- It has fewer than four sides
- Its angles are not all equal
- Its angles are not right angles
- Its sides are not all equal
Answer: D. A regular polygon needs equal sides and equal angles. A rectangle has equal angles but unequal adjacent sides.
Sample question 3
An architect builds a model of a building to a scale of 1 : 20. The model's roof has an area of 3 m². What is the area of the actual roof?
- 60 m²
- 24,000 m²
- 240 m²
- 1200 m²
Answer: D. Lengths scale by 20, so areas scale by 20² = 400. Area = 3 × 400 = 1200 m².
