Meenakshi is interested in arts and one day while painting on a paper she discovered that the paper upon folding across a line overlapped exactly with the other part. This line can be termed as-
Line of symmetry
Line of division
When we are able to fold a picture in a half such that the left and right halves match exactly then we say that the picture has a line of symmetry. Line of symmetry is otherwise called reflection symmetry since one half is the reflection of the other half.
