P2 Quadrilaterals: Paper 1 Basics
P2 Quadrilaterals: Paper 1 Basics
This paper starts from the definitions: sides and corners of a quadrilateral, the right angles of a rectangle, equal sides of a square, simple perimeters, and a correction of the idea that a circle is a quadrilateral.
Direct answers Answers: 1 four sides; 2 four corners; 3 four right angles; 4 all sides equal; 5 1 more; 6 20 centimetres; 7 18 centimetres; 8 one pair; 9 both pairs parallel and equal; 10 a circle is not a quadrilateral.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | Four sides. A quadrilateral has four straight sides and four corners. | Count the straight lines around the shape: there are always four. |
| 2 | Four corners. Every pair of neighbouring sides meets at one corner. | Each meeting of two sides forms a corner, so four sides give four corners. |
| 3 | Four right angles. All four corners of a rectangle are 90 degrees. | Check with the right angle of a set square: all four corners fit. |
| 4 | All four sides are equal. A square has equal sides and four right angles. | A square adds equal sides to the right angles of a rectangle. |
| 5 | 1 more. 4 minus 3 is 1. | Subtract the number of triangle sides from the quadrilateral sides. |
| 6 | 20 centimetres. 5 times 4 is 20. | The perimeter adds all four equal sides, so multiply by four. |
| 7 | 18 centimetres. 6 + 3 + 6 + 3 = 18. | A rectangle has two lengths and two widths, so (6 + 3) times 2 also works. |
| 8 | One pair. Only one pair of opposite sides is parallel; the other pair is not. | Parallel sides never meet however far they are extended. |
| 9 | Both pairs of opposite sides are parallel and equal in length. | Slant the shape and the lengths and the parallel pairs stay the same. |
| 10 | No. A circle has no straight sides and no corners, while a quadrilateral must have four straight sides and four corners. | Two tests decide it: four straight sides and four corners, both required. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
