What different shapes have 2 lines of symmetry?

Answer 1

The only known shapes with two lines of symmetry are rhombus and rectangles. These shapes are found by the test of line of symmetry of certain shapes.

1. Sketch a rectangle, which has two pair of congruent and parallel lines and all right angles. Indicate the lines of symmetry. They should pass through each opposite midpoint of the segments of the rectangles.
2. Sketch a rhombus, the shape that has all congruent sides, but have two pairs of congruent angles, which are different from another. Indicate the lines of symmetry. They should pass through both opposite vertices of the rhombus.
