All i need is a flow chart for this

A triangle is said to be equilateral if all three of its sides are equal; isosceles if any two sides are equal and scalene if no sides are equal. Draw a flow chart that would allow the user to enter three sides of a triangle and then determine into which of the above categories it falls. Remember that in order for the sides to make a triangle, the sum of any two sides must be greater that the third side. Be sure that the data provided would be a valid triangle before determining what kind of triangle it is.
