Question

How many digits have no line of symmetry? Write them.$7$

Answer 1

Step 1: Draw the vertical lines on each number and check whether the numbers are symmetrical or not.

Step 2: It can be noticed that only the digit $8$ has a vertical line of symmetry.

Step 3: Draw the horizontal lines on each number and check whether the numbers are symmetrical or not.

Step 4: It can be noticed that only the digits $3$ and $8$ have a horizontal line of symmetry.

Hence, the digits $1$, $2$, $4$, $5$, $6$, $7$ and $9$ have no line of symmetry.
