Parallelogram
In Euclidean geometry, a parallelogram is a simple (non self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean Parallel Postulate and neither condition can be proven without appealing to the Euclidean Parallel Postulate or one of its equivalent formulations. The three-dimensional counterpart of a parallelogram is a parallelepiped. The etymology (in Greek παραλληλ-όγραμμον, a shape "of parallel lines") reflects the definition. A simple (non self-intersecting) quadrilateral is a parallelogram if and only if any one of the following statements is true:12 Two pairs of opposite sides are equal in length. Two pairs of opposite angles are equal in measure. The diagonals bisect each other. One pair of opposite sides are parallel and equal in length. Adjacent angles are supplementary. Each diagonal divides the quadrilateral into two congruent triangles. The sum of the squares of the sides equals the sum of the squares of the diagonals. (This is the parallelogram law.) It has rotational symmetry of order 2.
The Urban Dictionary Mug
Soaking is my favorite activity, glad I got a mug for it 😙
It DIDNT break :D
so happy you were able to put my unique word "Obergrossescheinehund" onto the new yellow mug. The yellow mug and black print make it easy for the words to be seen.
This is made by my friend i love it
Imagine not buying one of these. 🤢🗑🤡= non-buyer. Couldn't be me. 😎
It was the best thing I could have asked for
I mollywopped someone with it and it didn’t break. Nice
Product was as advertised and arrived pretty quickly too! The person loved their gift!
The "Pink Flamingo" colour with white text on a pink background is the best selection for this fine phrase mug. May I suggest you also correct the misspelling of "delightfully" in the default option for a timeless gift.
As always, a great gift.
