Can a quadrilateral with four equal sides have less than four lines of symmetry?

Yes, a quadrilateral with four equal sides can have less than four lines of symmetry.

Step-by-step explanation:

Yes, a quadrilateral with four equal sides can have less than four lines of symmetry.

A line of symmetry is defined as a line that line which divides a figure into two mirror image halves.

A quadrilateral is a 4-sided plane shape like square, rectangle, or irregular quadrilaterals.

A quadrilateral with four congruent sides and four right angles is a square and a square is both a rhombus and a rectangle.

But a square has 4 lines of symmetry.

And a rectangle and rhombus have 2 lines of symmetry.
