Triangle Inequality Theorem The sum of the lengths of any two sides of a triangle is greater than the length of the third side. Third Side Rule The length of any one side of a triangle must be less than the sum of the other two sides, and greater than the difference between the other two sides. Slope Formula m = (y2 - y1) / (x2 - x1) Point Sloe Equation (y-y1) = m(x-x1) Slope-Intercept Form y=mx+b, where m is the slope and b is the y-intercept of the line. ...
