Polygon Angles

For any polygon of n sides:

Four Circle Formulas

Circumference = 2πr = πd

Parallelogram:

Area    of  Parallelogram   =   base    ×   height

2.

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°

Sum of  Exterior    Angles  =   360°
