03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 360 degrees | A quadrilateral splits into two triangles, and 180 times 2 = 360 degrees. |
| 2 | A square | Four equal sides plus four right angles make a square. |
| 3 | A rectangle | Four right angles without equal sides give a rectangle; if the sides are equal too, it is a square. |
| 4 | A parallelogram | Both pairs of opposite sides parallel give a parallelogram; squares, rectangles and rhombuses are special cases. |
| 5 | A trapezium | Exactly one pair of opposite sides parallel gives a trapezium. |
| 6 | A rhombus | Four equal sides without right angles give a rhombus; with right angles it becomes a square. |
| 7 | Yes, a square is a special rectangle | A square has four right angles, so it meets the definition of a rectangle and adds four equal sides. |
| 8 | 90 degrees | 360 minus 80 minus 100 minus 90 = 90 degrees. |
| 9 | 110 degrees | Adjacent angles of a parallelogram add to 180°, so 180 minus 70 = 110 degrees. |
| 10 | No, it may only be a rectangle | Four right angles only prove it is a rectangle; the four sides must also be equal to make a square. |
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.
