Detailed explanation-1: -Symmetry in Mathematics Consider an example, when you are told to cut out a ‘heart’ from a piece of paper, don’t you simply fold the paper, draw one-half of the heart at the fold and cut it out to find that the other half exactly matches the first half? The heart carved out is an example of symmetry.

Detailed explanation-2: -Symmetrical relationship can be observed when two variables fluctuate at the same time. However, in symmetrical relationship change in one variable is not caused by change in another variable. In other words, symmetrical relationships of two individual variables usually would be the cause of another factor.

Detailed explanation-3: -What is Symmetry in Math? Symmetry is defined as a proportionate and balanced similarity that is found in two halves of an object, that is, one-half is the mirror image of the other half. For example, different shapes like square, rectangle, circle are symmetric along their respective lines of symmetry.

Detailed explanation-4: -For example, an isosceles triangle has one line of symmetry, the rectangle has two lines of symmetry, and the circle has an infinite line of symmetry.
