The points: A(0,0) B(3,4) C(8,0) form a triangle.
a) Find the exact length of AB.
b) Find the equation of AB.
c) Find the perpendicular distance from C to the line AB.[/quote]
a) Use distance formula
- where and
b) This is simply using the equation of a line formula for two point
where is the slope of the line between the two points. Im not too sure whether your able to find this so use see definations of the points above.
c)Not too sure about this but im sure someone wiser will tell you. Maybe the following where is the point and is the line
