Triangle

Perimiter = side 1 + side 2 + side 3 / Area 1/2 bh

Square

s = side / perimeter = 4s / Area = s x s or s squared

Rectangle

b = base / h = height / Perimeter = 2(b+h) / area = bh

Parallelogram

l = length / w = width / Perimeter = 2(l+w) / Area - 1/2h (b1+b2)

Trapezoid

Perimeter = b1 + b2 + s1 + s2 / Area = 1/2h (b1 + b2)

Circle

P = Pie / r = Radius / d = diameter / Circumfrance 2πr or πd / Area = pr -squared

Pythagorean Theory

a2 + b2 = c2

Cube

Volume = s x s x s or s cubed (3)

Rectangular Prism

Volume = L x W x H / Surface = 2(lw) + 2(lh) + 2(wh)
