Rectangles and Parallelograms?

Question

why is a rectangle a parallelogram and please don't tell me it's because a rectangle is a bent parallelogram.

Answer 1

A rectangle is a special kind of parallelogram. Opposite pairs of sides are parallel to each other in a rectangle, and each angle of a rectangle is a right angle (90°). So, all rectangles are parallelograms, but not all parallelograms are rectangles.

Answer 2

A parallelogram is defined as having two sets of opposite parallel sides. A rectangle fits this definition, and so it is a parallelogram. It fits it because all the interior angles of a rectangle are right angles. This means that each vertex is composed of two perpendicular segments. Since for every side there are two other sides that are perpendicular to it, these two other sides are parallel. Because of this, both sets of opposite sides are parallel, and so the rectangle fits the definition of a parallelogram.

Answer 3

a rectangle is a parallelogram cus both a rectangle and a parallelogram have 2 sets of equal sides. the top and bottom r equal 2 each other and the 2 sides r equal 2 each other.

Answer 4

Parallelogram means that each side of the object is parallel to the one directly across from it. Since a rectangle looks like this:

1---------------1
1---------------1

(Well, sort of...you get the idea...) the "1's" are parallel and the "----" is parallel. Hence, a rectangle is a parallelogram.

Answer 5

Technically, a parallelogram is any quadrilateral with two pairs of parallel sides. So yes, they are parallelograms.
