Question

5. How many lines of symmetry does the figure below have? if there are no lines of symmetry, write none.

Answer 1

There would be 8 lines of symmetry for this shape. 

Answer 2

Lines of symmetry are lines that are the same but opposite to each other. For example, a rectangle has 2 lines of symmetry since it has 4 sides and 2 groups of symmetrical lines.
This shape is an octagon, which has 8 sides and 4 groups of symmetrical lines.

So the answer is C. 4.
