Q1. According to the chapter, what does ‘symmetry’ refer to?
- A part or parts of a figure repeated in some definite pattern
- Any bright colour
- A figure with curved edges
- A shape with many sides
Show answer
Answer: A. A part or parts of a figure repeated in some definite pattern
Why: The flower, butterfly, rangoli and pinwheel have repeating patterns; the clouds do not. [p.218]
Why: The flower, butterfly, rangoli and pinwheel have repeating patterns; the clouds do not. [p.218]
Q2. A line that cuts a figure into two parts that exactly overlap when folded along it is called a line of ______.
Show answer
Answer: symmetry
Why: The two parts are mirror halves; the fold line is a line of symmetry (axis of symmetry). [p.219, p.241]
Why: The two parts are mirror halves; the fold line is a line of symmetry (axis of symmetry). [p.219, p.241]
Q3. How many lines of symmetry does a square have?
Show answer
Answer: 4 (± 0)
Why: Folding vertically, horizontally and along both diagonals gives 4 lines of symmetry. [p.220–221]
Why: Folding vertically, horizontally and along both diagonals gives 4 lines of symmetry. [p.220–221]
Q4. A figure that has one or more lines of symmetry is also said to have ______ symmetry.
- reflection
- rotational
- no
- circular
Show answer
Answer: A. reflection
Why: The part on one side of the line is reflected to the other side, so we call it reflection symmetry. [p.222]
Why: The part on one side of the line is reflected to the other side, so we call it reflection symmetry. [p.222]
Q5. In the ink blot activity, where is the line of symmetry of the pattern?
- Along the fold of the paper
- Along the edge of the paper
- There is none
- Across the corner
Show answer
Answer: A. Along the fold of the paper
Why: Pressing the halves together copies the blot to the other side of the fold, which becomes the line of symmetry. [p.222]
Why: Pressing the halves together copies the blot to the other side of the fold, which becomes the line of symmetry. [p.222]
Q6. A paper windmill looks the same after a 90° turn but has no line of symmetry. What kind of symmetry does it have?
- Rotational symmetry
- Reflection symmetry only
- No symmetry
- Line symmetry
Show answer
Answer: A. Rotational symmetry
Why: Looking exactly the same after a rotation about a point is rotational symmetry. [p.230]
Why: Looking exactly the same after a rotation about a point is rotational symmetry. [p.230]
