the restriction on a parallelogram is that the opposite sides be parallel. There are more restrictions on a rectangle since we also require that we have 4 right angles.

Is a rectangle a parallelogram Why?
yes, a rectangle is a parallelogram. A parallelogram is a polygon (closed shape with straight sides) that has exactly 2 pairs of parallel sides. A rectangle is a parallelogram with 4 right angles(90o). "Rectangle" is more specific. So all rectangles are parallelogram but not all parallelograms are rectangles.
How is a parallelogram different from a rhombus?
Technically, a rhombus is a parallelogram, but a parallelogram is not always a rhombus. A parallelogram is any four-sided shape with two sets of parallel lines. A rhombus is a parallelogram with all equivalent side lengths. So, a rhombus is a more specific parallelogram. (And so is a a square or a rectangle.)
How are a trapezoid and a parallelogram different?
A trapezoid and parallelogram are both quadrilaterals. Their top and bottoms are parallel. In a parallelogram, all four sides are parallel making it look like a rectangle that was pushed on an angle. The trapezoid is more like the shape of an "A" with a square top.
What polygon has one more vertex than a rectangle?
parallelogram
Are all parallelograms a square?
No. A parallelogram by definition is a quadrilateral that has two pairs of parallel sides. A square by definition is a parallelogram with 4 congruent sides and angles (each measuring 90 degrees). So there are more finite requirements that must be fulfilled for a shape to be a square. A parallelogram doesn't have to be a square--it could be a rectangle, for instance. Or, it could be just a parallelogram--nothing more. However, a square isalways a parallelogram. :)

Why a rectangle a parallelogram?
Because a rectangle meets all the requirements of a parallelogram - and more.

What is the perimeter of a parallelogram with a an area of 60?
It can be any length you like greater than (or equal to) 4 x √60 ≈ 30.98 A parallelogram is a sheared rectangle; the more the rectangle shears, the longer the originally "vertical" sides (the height of the parallelogram) become. (Shearing does not change the area of the shape.)
What is the definition of parallelogram?
A parallelogram can be considered as a slanted rectangle.

What shape has 4 sides and 2 of them are equal?
A quadrilateral. As far as I know there isn't a more specific term; a quadrilateral with two equal sides may also be, but certainly doesn't have to be, a rectangle, square, rhombus, trapezoid, and/or parallelogram.

Which has a bigger area - a parallelogram or a rectangle?
A big parallelogram has more area than a small rectangle. A small parallelogram has less area than a big rectangle. The question is a lot like asking: "Which one is older, a dog or a cat ?"
Why is a square a rectangle?
A rectangle is a parallelogram with angles of 90 degrees. A square has those properties (and more) so it is a rectangle.
What polygon has one more vertex than a rectangle?
parallelogram
