Chapter-9 Symmetry — Important Questions & Answers
What is a line of symmetry?
- A. A line that divides a shape into two identical mirror images
- B. A line that divides a shape into two equal parts of any kind
- C. A line that goes through the center of any shape
- D. A line that makes a shape rotate
Answer: A. A line that divides a shape into two identical mirror images
A line of symmetry is a line along which a figure can be folded so that the two halves match exactly, creating mirror images.

How many lines of symmetry does a square have?
- A. 1
- B. 2
- C. 3
- D. 4
Answer: D. 4
A square has 4 lines of symmetry: 2 diagonal lines and 2 lines through the midpoints of opposite sides.

Which letter does NOT have any line of symmetry?
- A. H
- B. I
- C. F
- D. V
Answer: C. F
The letter 'F' has no line of symmetry because there is no line that divides it into two identical mirror images.
The letter 'F' has no line of symmetry because there is no line that divides it into two identical mirror images.
A design is made by reflecting a pattern across a vertical line 3 times alternately. Which statement is true?
- A. The final design will have only 1 line of symmetry
- B. The final design will have 3 lines of symmetry
- C. The final design will have no lines of symmetry
- D. The final design depends on the original pattern
Answer: D. The final design depends on the original pattern
The number of lines of symmetry in the final design depends on the symmetry properties of the original pattern being reflected.
The number of lines of symmetry in the final design depends on the symmetry properties of the original pattern being reflected.
In a symmetrical design created by folding paper along a line and cutting shapes, if you cut a triangle from one side, what shape appears on the other side when unfolded?
- A. A different polygon
- B. An identical triangle (mirror image)
- C. No shape appears
- D. A larger triangle
Answer: B. An identical triangle (mirror image)
When paper is folded and cut, the cut creates a mirror image on the other side of the fold line, so cutting a triangle produces an identical triangle when unfolded.
