Why does a square have more lines of symmetry than a rectangle?
The diagonals of a rectangle aren't lines of symmetry unless it's square.
What shape has more than one line of symmetry?
A circle (infinitely many lines of symmetry), ellipse, rectangle, and all regular polygons.
How does a rectangle have two lines of symmetry?
To see this more clearly, take a piece of paper that is rectangular in shape and fold in half from top to bottom. When you unfold you will see the crease through the middle of the paper and notice that both halves are symmetrical, meaning mirror images of each other, and identical in size and shape. Now, fold the paper in half again from left to right. When you unfold you will see a second crease, forming a cross over the first. The two creases represent the two lines of symmetry. Note: Technically a square is also a rectangle, but has 4 lines of symmetry since you can also divide a square into symmetrical shapes from the corners, or on the diagonal.
Does a triangle have more than 1 line of symmetry?
Depending on the triangle, there can be 0, 1, or three lines of symmetry. A scalene triangle (all sides of different lengths) will have no lines of symmetry, an isosceles triangle (exactly two sides of the same length) will have one line of symmetry, and an equilateral triangle (all three sides of the same length) will have three lines of symmetry.
With 27 sides how many lines of symmetry does a polygon have?
No more than 27.
