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 congruent parts that are mirror images of each other.

Step2: Check the figure

If we fold the figure along the dotted line, the left - hand side and the right - hand side do not match exactly. For example, the leftmost tulip has no corresponding tulip on the right side in a symmetric way.

Answer:

no
