To find the length of a diagonal, use the Pythagorean Theorum: | ||

Area of a Rectangle = length x width: | ||

Area of a Triangle = 1/2 the base x altitude: | ||

Area of a Trapezoid = 1/2 Altitude(base 1 + base 2): | ||

Area of an Equilateral Triangle = | ||

Area of a Parallelogram = base x altitude | ||

Area of a Rhombus = 1/2 (d1 x d2) | ||

Comparing Equivalent Triangles = If two triangles have equal bases and equal altitudes, then their areas are equal | ||

(pi) = 3.1415926... | ||

Area
of a Circle = pi x radius squared = r^{2} |
