Worksheet of Symmetry and Practical Geometry for Grade 6

1. How many lines of symmetry are there in the given figure?

cmo-symmetry-c6-21

a) One line of symmetry
b) Two lines of symmetry
c) Three lines of symmetry
d) Four lines of symmetry

Answer: d) Four lines of symmetry

Explanation: There are four lines of symmetry, shown as:

cmo-symmetry-c6-22

2. Which of the following is mirror-image symmetry?

a) cmo-symmetry-c6-23
b) cmo-symmetry-c6-24
c) cmo-symmetry-c6-25
d) cmo-symmetry-c6-26

Answer: d) cmo-symmetry-c6-27

Explanation: All the letters are correctly reflected and of the same size in option (d).

3. What is the difference in the number of lines of symmetry of the given figures?

cmo-symmetry-c6-28

a) 0
b) 1
c) 2
d) 4

Answer: c) 2

Explanation: The lines of symmetry in the figures are shown as:

cmo-symmetry-c6-29

Difference in the number of lines of symmetry = 4 − 2 = 2

4. Which of the following figures have a horizontal line of reflection symmetry?

a) cmo-symmetry-c6-30
b) cmo-symmetry-c6-31
c) cmo-symmetry-c6-32
d) cmo-symmetry-c6-33

Answer: c) cmo-symmetry-c6-34

Explanation: The figures show the line of symmetry of the figures:

cmo-symmetry-c6-35
