P3 Parallel and Perpendicular: Paper 1 Basics
P3 Parallel and Perpendicular: Paper 1 Basics
This paper first separates parallel from perpendicular, then drills the right angle of 90 degrees and the sides of rectangles and squares, introduces the two symbols, and closes with a common misconception. Every item has an answer and a one-line note.
Direct answers Items 01 to 03 cover definitions and the right angle, 04 to 06 the sides of rectangles and squares plus the set square, 07 to 09 the symbols and a real example, and 10 corrects the idea that lines which do not touch are parallel.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | Parallel lines. | The key points are same plane and still no meeting after extending. |
| 2 | They are perpendicular to each other. | Two lines that meet at 90 degrees are perpendicular. |
| 3 | 90 degrees. | A right angle is 90 degrees and is the usual benchmark angle. |
| 4 | Parallel. | A rectangle has two pairs of parallel opposite sides. |
| 5 | 90 degrees. | A square has four equal sides and every neighbouring pair meets at 90 degrees. |
| 6 | The right-angle corner. | Only the right angle can fit a perpendicular crossing exactly. |
| 7 | The symbol is two parallel short strokes, written a parallel b. | Parallel is shown by two short parallel strokes. |
| 8 | The symbol is one stroke on another, read as perpendicular to. | Perpendicular is shown by the T-shaped symbol. |
| 9 | Parallel. | They run in the same direction at a constant distance, so they are parallel. |
| 10 | Wrong. They must be in the same plane and still not meet after extending. | Lines in different directions can also miss each other without being parallel, so check the direction. |
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.
