Name	Shape	Formulas
Rectangle		$\begin{matrix} Perimeter: P = 2 l + 2 w \\ Area: A = l w \end{matrix}$
Square		$\begin{matrix} Perimeter: P = 4 s \\ Area: A = s^{2} \end{matrix}$
Triangle		$\begin{matrix} Perimeter: P = a + b + c \\ Area: A = \frac{1}{2} b h \\ Sum of Angles: A + B + C = 180° \end{matrix}$
Right Triangle		$\begin{matrix} Pythagorean Theorem: a^{2} + b^{2} = c^{2} \\ Area: A = \frac{1}{2} a b \end{matrix}$
Circle		$\begin{matrix} C = 2 π r \\ Circumference: & or \\ C = π d \\ Area: A = π r^{2} \end{matrix}$
