P3 Parallel and Perpendicular: Paper 2 Intermediate
P3 Parallel and Perpendicular: Paper 2 Intermediate
Counting comes first: parallel sides, perpendicular sides, the 4 right angles of a crossing, the constant gap between parallels, and then a short chain of reasoning. Answers and notes are included.
Direct answers Items 01 to 03 count parallel pairs, the 90 degree corners and the right angles of a crossing, 04 to 06 cover constant distance, the chain of parallel and perpendicular, and the total of four angles, 07 to 09 cover grid paper, extending a line and neighbouring perpendicular sides, and 10 corrects a length misconception.

- FoundationHow many pairs of opposite sides of a rectangle run parallel?
- FoundationEach corner of a rectangle measures how many degrees?
- FoundationWhen two perpendicular lines cross, how many right angles surround the crossing point?
- IntermediateIs the gap between two parallel lines constant wherever you measure it?
- IntermediateSuppose a runs parallel to b and b runs perpendicular to c. What about a and c?
- IntermediateA square has two parallel pairs and perpendicular neighbours; its four angles total what?
- ChallengeOn grid paper, what direction does a line parallel to the horizontal grid lines take?
- ChallengeIf a line is extended by 10 cm, will a line parallel to it cross it?
- ChallengeEach corner of a rectangle joins one perpendicular pair of sides. How many such pairs in one rectangle?
- Error redoCorrect this: two perpendicular lines must be the same length.
03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 2 pairs. | Rows above and below form one pair and the two uprights form another: 2 pairs. |
| 2 | 90 degrees. | All four corners are right angles, so each is 90 degrees. |
| 3 | 4. | A crossing makes 4 angles and perpendicular lines make every one of them 90 degrees. |
| 4 | Yes, it is constant. | Matching directions mean every perpendicular between them is equally long. |
| 5 | They are perpendicular. | a follows b, and b is 90 degrees to c, so a is 90 degrees to c. |
| 6 | 360 degrees. | Four angles of 90 degrees come to 360 degrees. |
| 7 | Horizontal, along the same row as the grid lines. | Grid lines are parallel to each other, so a line drawn in the same direction is horizontal. |
| 8 | No. | Parallel lines never meet no matter how far they are extended. |
| 9 | 4 pairs. | Four corners give 4 perpendicular pairs, so 4 pairs in all. |
| 10 | Wrong. Perpendicular only means the crossing angle is 90 degrees, nothing about length. | A short hand and a long hand can still be perpendicular; different lengths do not matter. |
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.
