The points P(0, 6), Q(-5, 3) and R(3, 1) are the vertices of a triangle, which is

The distance between any two points P1(x1, y1) and P2(x2, y2) is given by the following formula:



Distance AB =


= √(25 + 9)


= √34


Distance BC =


= √(64 + 4)


= √68


Distance AC =


= √(9 + 25)


= √34


Since the length of two sides is equal, given triangle is an isosceles triangle.


The given triangle also satisfy Pythagoras Theorem in following way:


BC2 = AC2 + AB2


Therefore the given triangle is also right-angled triangle.
