Answer to Question 1 (4 marks)
1. Compare each angle with a right angle. The first is smaller than a right angle, so it is acute (about 35°). The second is a square corner, a right angle (90°). The third is bigger than a right angle but less than a straight line, so it is obtuse (about 140°) (3 marks: 1 for each).
2. A quarter turn is a quarter of a full turn of 360°: 360° ÷ 4 = 90°. So the quarter turn is the right angle (1 mark).
Answer to Question 2 (4 marks)
1. Two sides are equal (6 cm and 6 cm) and the third is different, so the triangle is isosceles (1 mark).
2. Hexa means six, so a hexagon has 6 sides; octa means eight, so an octagon has 8 sides (2 marks: 1 for each).
3. A regular pentagon has 5 equal sides of 7 cm. Perimeter = 5 × 7 = 35 cm (1 mark).
Answer to Question 3 (4 marks)
1. A rectangle folds exactly in half across the middle and down the middle, so it has 2 lines of symmetry (1 mark).
2. A kite only folds onto itself along the line through its top and bottom corners: 1 line (1 mark).
3. An equilateral triangle has a line from each corner to the middle of the opposite side: 3 lines (1 mark).
4. A square has exactly 4 lines of symmetry: across, down and the two diagonals (1 mark). A regular quadrilateral is the same shape, so it also gets the mark.
Answer to Question 4 (4 marks)
1. At 5 o'clock the minute hand points to 12 and the hour hand to 5. There are 5 hour gaps between them, each 30°: 5 × 30° = 150° (2 marks: 1 for counting 5 gaps, 1 for 150°).
2. 150° is more than a right angle (90°) but less than a straight line (180°), so it is an obtuse angle (1 mark).
3. A right angle is 90°, and 90° ÷ 30° = 3 hour gaps. So the hands make a right angle at 3 o'clock (or 9 o'clock) (1 mark).
Answer to Question 5 (4 marks)
1. A regular hexagon has 6 equal sides of 10 cm: 6 × 10 = 60 cm (1 mark).
2. A regular hexagon has as many lines of symmetry as sides: 6 lines (1 mark).
3. Each square adds 10 cm to the length: 30 × 10 = 300 cm. 100 cm = 1 m, so the row is 3 m long (1 mark).
4. Yes. A square has 4 equal sides, so its perimeter is 4 × 10 = 40 cm, which matches the 40 cm given (1 mark).

How to use these Year 4 angles, shapes and symmetry test answers

First, sit the test under timed conditions before you read anything here. Then mark each answer and give yourself the marks shown, including method marks. When you lose marks, read the worked solution and find the step you missed. After that, revise the angles, shapes and symmetry lesson and redo the worksheet.

Also, the Year 4 angles, shapes and symmetry test answers are available as a PDF, so a teacher can mark printed tests quickly. Moreover, all the pages of this chapter work together, so you can move between them at any time. For example, many pupils read the lesson on Monday, practise on Wednesday and test themselves on Friday.
