Question

is the dotted line a line of symmetry?

Explanation:

Step1: Recall the definition of line of symmetry

A line of symmetry divides a figure into two mirror - image halves.

Step2: Check the given figure

When we consider the dotted line, if we were to fold the figure along this line, the left and right parts would not match exactly (because of the position of the white circles in the green liquid part).

Answer:

no
