-- trapezoid -- kite -- four-sided figure with no two equal sides
A parallelogram has two sets of sides that are parallel to each other. A trapezoid only has one set of sides that are parallel.
Isosceles trapezoid.
Another trapezoid that has the same dimensions and angles will be congruent to it.
If a parallelogram has all four sides the same length it's called a square.
No, it is not.
They are not.
No.
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
No.
Rectangle.Note:It's enough to say that it has one right angle, and the result is the same.
