In a parallelogram:
the opposite sides are parallel and congruent,
the opposite angles are congruent,
the consecutive angles are supplementary,
the diagonals bisect each other, and
a diagonal divides it into two congruent triangles.
to be simple both sides are congruent and both sides are parallel
A rectangle has 4 right angles whereas a parallelogram has no right angles.
All rectangles have
A parrellelogram is a square with 2 parallel sides. The facing sides are of the same length.
rectangle, quadrilateral, and parallelagram
a rhombus has all equal sides but a parallelagram only has two equal sides.
Yes , yes it is true :)
yes, but there are other shapes too.
A rectangle or a square.
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
Some of them are, but not all of them. A parallelogramis a rectangle only if all of its angles are equal.
Yes it is. A square is a quadrilateral, a parallelogram, a rhombus, and a rectangle.
