# triangleareabycoordinates(x1, y1, x2, y2, x3, y3)[5pts]
# Write the function triangleareabycoordinates(x1, y1, x2, y2, x3, y3) that takes 6 int or float
# values that represent the three points (x1,y1), (x2,y2), and (x3,y3), and returns as a float the
# area of the triangle formed by those three points. Hint: you should make constructive use of
# the triangleArea function you just wrote above.

def triangleareabycoordinates(x1, y1, x2, y2, x3, y3):
	Area = abs((0.5)*(x1*(y2-y3)+x2*(y3-y1)+x3*(y1-y2)))
	return Area
