Total Marks: 40
Topic: Geometry (syllabus-first; not from past papers)
Section A Answers (1 mark each)
1. Right angle
Teaching note: A square corner is a right angle (90°). The corner of a square is the standard example.
2. B) The corner of a book
Teaching note: A book corner is square, so it is a right angle. A sloping roof and pencil tip are not right angles.
3. Parallel
Teaching note: Parallel lines never meet and stay the same distance apart.
4. Perpendicular
Teaching note: Perpendicular lines meet at a right angle (square corner).
5. Acute
Teaching note: An angle smaller than a right angle is called acute. (P3 uses "smaller than a right angle" mainly, but acute is the term.)
6. Obtuse
Teaching note: An angle bigger than a right angle is called obtuse.
7. Smaller than a right angle
Teaching note: The shaded angle is lightly shaded and the square shows the right angle; shaded is clearly less open than the square corner.
8. Parallel
Teaching note: The two horizontal lines have arrowheads and never meet; they are parallel to each other. The vertical line is perpendicular to them.
9. 4
Teaching note: A rectangle has four square corners, so 4 right angles.
10. B) Square
Teaching note: A square has 4 equal sides and 4 right angles. A rectangle has right angles but not always equal sides.
Section B Answers (2 marks each)
11. [Drawing expected: an L-shape with a small square at the corner]
Marking: 1 m for correct corner shape, 1 m for square mark.
Teaching note: Use ruler to make two lines meeting as a square corner; draw a small square to show it is 90°.
12. Parallel. The two vertical lines of H never meet and are same distance apart.
Marking: 1 m name, 1 m reason.
Teaching note: In H, left and right strokes are vertical and do not touch; they are parallel.
13. Right-angled triangle
Marking: 2 m for correct name.
Teaching note: A 3-sided shape is a triangle; with one right angle it is a right-angled triangle.
14. Smaller than a right angle
Marking: 2 m for correct comparison using diagram.
Teaching note: Dark shaded corner is less open than the square-marked right angle.
15. Any two, e.g., edge of desk and leg of desk; page of book and spine.
Marking: 1 m each correct object (2 m total).
Teaching note: Perpendicular lines meet at right angles; furniture corners are good examples.
16. Railway tracks run side by side and never meet, always same distance apart, so they are parallel.
Marking: 2 m for correct explanation.
Teaching note: Parallel means no meeting and equal gap; tracks show this.
Section C Answers (3 marks each)
17.
(a) 4 right angles (1 m)
(b) Yes, opposite sides of a rectangle are parallel because they never meet and are equal distance apart. (2 m: 1 for yes, 1 for reason)
Teaching note: Rectangle properties: 4 square corners, opposite sides parallel.
18.
(a) Perpendicular lines (1 m)
(b) Yes, the steps are parallel because they are horizontal, same distance apart, and never meet. (2 m: 1 yes, 1 reason)
Teaching note: Step treads are like parallel lines; side is perpendicular to them.
19. [Drawing: rectangle or square with opposite sides marked with arrows] Name: Rectangle (or Square). (3 m: 1 draw, 1 pairs parallel labelled, 1 name)
Teaching note: Rectangle has 2 pairs of parallel opposite sides and 4 right angles.
20.
(a) The angle with the square mark (1 m)
(b) Greater than a right angle (1 m)
(c) Any adjacent sides meeting at square mark, e.g., the two lines forming the right angle (1 m)
Teaching note: Square mark = right angle; shaded is more open = greater; those two lines are perpendicular.
