Polygon Angles

For any polygon of n sides:

Trapezoid:

1.

2. Parallelogram: Area  of  Parallelogram   =   base    ×   height

Rectangle: Perimeter    of  Rectangle   =   2(length    +   width) Area of

Rectangle   =   length  ×   width

3.

Rhombus (four   equal   sides): Perimeter   of  Rhombus =   4   ×   side Area

of  Rhombus =   base    ×   height

4.

Square  (four   right   angles  and four    equal   sides): Perimeter   of

Square  =   4   ×   side Area   of  Square  =   (side)^2

5.

Sum of  Interior    Angles  =   (n  –   2)  ×   180°
