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.
