For a right isosceles triangle (45-45-90), there is one line of symmetry that bisects the hypotenuse. For all other right triangles, there are zero lines of symmetry.

The quadrilateral that has two lines of symmetry that are diagonals is a rhombus. In a rhombus, the diagonals bisect each other at right angles and serve as lines of symmetry. Each diagonal divides the rhombus into two congruent triangles, reflecting the shape across the diagonal. This property gives the rhombus its two lines of symmetry.
