A parallelogram has no lines of symmetry unless it is a square, a rectangle or a rhombus.
A kite is not a parallelogram because the parallelogram's angles are tilted and a kite isn't.
Because it is formed of pairs of parallel lines.
A quadrilateral that is not a parallelogram (two sets of parallel sides) may be a trapezoid or a trapezium (US terms). To draw a trapezium (irregular quadrilateral), draw two parallel lines and connect them with unequal lines at non-congruent angles. If you make the angles opposite and congruent, you have drawn a trapezoid, which looks like a small stepstool with a top smaller than the base. If you make the connecting lines of equal length, you have drawn a trapezoid or parallelogram.

square, rectangle, parallelogram, rhombus, triangle, kite
how many triangles are formed when any parallelogram and it diagonals are drawn
A kite is not a parallelogram because the parallelogram's angles are tilted and a kite isn't.
a parallelogram with four equal sides must be a square. therefore, a line can be drawn diagonally (crossing through the middle, and touching the corners) on the upper left to the lower right, and from upper right to lower left. Also, a line can be drawn vertically and horizontally in the exact middle. that makes 4 lines of symmetry.
A parallelogram need have no lines of symmetry.
because both lines are paralle so it is a parallelogram
A parallelogram has two pairs of opposite congruent lines
parallelogram
no it does not
A parallelogram has 2 pairs of parallel lines
Planes are not necessarily drawn as parallelograms. The Cartesian plane is drawn as a rectangle and, contrary to what the previous answerer [ignorantly] claimed, it does have a ninety degree angle where the axes meet. The representation of a plane in 3-d space is often depicted as a parallelogram in much the same way that the drawing of a cube has parallelograms for its lateral faces. A parallelogram is a compromise between lines of perspective (which should meet at the centre of perspective) and the wish to maintain the parallel nature of these edges.
