the triangle with vertices a(4,-1), b(3,1) and c (-4,-2)
find the distance between points
the distance between a(4,-1), b(3,1) is equal to the length of the side
the distance between a(4,-1), c (-4,-2) is equal to the length of the side
the distance between b(3,1), c (-4,-2) is equal to the length of the side
and the perimeter is:
