# Which is always a rhombus? Parallelogram, Trapezoid, Rectangle, or Square?

See expanation

Some definitions: Rhombus - Four sides, all the same length, with opposite sides parallel. Parallelogram - Four sides; two pairs of parallel sides. Trapezoid - Four sides, with at least one pair of parallel sides. Rectangle - Four sides connected at four right angles, thus giving two pairs of parallel sides. Square - Four sides, all the same length, all connected at right angles.

Between mentioned figures you can write following dependencies:

Every rhombus is a parallelogram and a trapezoid.

Appart from it you can say that:

Parallelogram is trapezoid, but not every trapezoid is a parallelogram (for example a right trapezoid is not a parallelogram because it has only one pair of parallel sides)

Rectangle is a parallelogram.

Square is a rectangle, parallelogram, trapezoid and rhombus.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- What is a right trapezoid?
- Two opposite sides of a parallelogram each have a length of #7 #. If one corner of the parallelogram has an angle of #(2 pi)/3 # and the parallelogram's area is #42 #, how long are the other two sides?
- Two opposite sides of a parallelogram have lengths of #12 #. If one corner of the parallelogram has an angle of #pi/4 # and the parallelogram's area is #45 #, how long are the other two sides?
- Two opposite sides of a parallelogram have lengths of #3 #. If one corner of the parallelogram has an angle of #pi/12 # and the parallelogram's area is #15 #, how long are the other two sides?
- Two rhombuses have sides with lengths of #12 #. If one rhombus has a corner with an angle of #pi/3 # and the other has a corner with an angle of #(3pi)/8 #, what is the difference between the areas of the rhombuses?
