Question

when is a figure said have a line symmetry? illustrate with examples.​

Answer 1

For example, take your face. When we draw a line down our face exactly at the centre, then the left side of our face is symmetric to our right side of the face. This defines symmetry. This line that divides a figure or shape or any image in identical halves then that figure is said to have a line symmetry

Answer 2

Step-by-step explanation:

if we fold the figure cut out exactly at the center vertically, its halves will be congruent. The line of the fold is the line of symmetry. Figures or shapes that have exact resemblance to its other part, when divided into two or more equal parts are called symmetrical.
