GMAT : Quadrilaterals Quiz

*Theme/Title: Quadrilaterals
* Description/Instructions
When considering quadrilaterals there are several important facts that will assist in answering the majority of the GMAT questions related to quadrilaterals.
Quadrilaterals can be classified in the following ways:
1. Square - has 4 right angles and four sides of equal length. Opposite sides are parallel
a. P = 4s
b. A = s2
2. Rectangle - has 4 right angles and opposite sides are parallel and equal length
a. P = 2l + 2w
b. A = lw
3. Parallelogram - opposite angles are equal. Adjacent angles are supplementary. Opposite sides are equal and parallel.
a. P = 2l + 2w
b. A = lw
4. Rhombus - All sides are equal, adjacent angles are supplementary, opposite angles are equal. Diagonals are perpendicular and bisect each other and the end angles.
a. P = 4s
b. A = 1/2 (diagonal 1 * diagonal 2)
5. Trapezoid - one pair of parallel sides
a. P = A + B + C + D (where A, B, C, D are sides of the trapezoid)
b. A = 1/2 (height)(base1 + base2)
