## Basic Shapes

### Circle

Area = $\pi r^2$
Circumference = $\pi d=2\pi r$

### Line

Distance between two poitns $(x_1,y_1)$ and $(x_2,y_2)$ $=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Mid point of two poitns $(x_1,y_1)$ and $(x_2,y_2)$ = $(\frac{x_2-x_1}{2},\frac{y_2-y_1}{2})$

Getting point that is k part from $(x_1,y_1)$ to $(x_2,y_2)$ $=(x,y)=(x_1+k(x_2-x_1)+k(y_2-y_1)$
