The number zero has rotational symmetry.
A zero technically has an infinite amount of lines of symmetry.
A parallelagram can be a square, which has four lines of symmetry or a rectangle which has two lines of symmetry but the generic parallelagram has zero lines of symmetry
Zero
A trapezoid can have zero lines of symmetry or one line of symmetry.
Zero
It can have anywhere from zero to four of them.
ZERO!
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.
zero, all the keys have different letters, numbers, or symbols
There are different kinds of triangles, some are symmetrical and some aren't.
A capital N has no lines of symmetry (nor semetry).
Four. * * * * * I would say just 2: horizontal and vertical.
