Finally, we should check to see if it's right-angled.

The vector AB is (-5, -5); AC is (-1, 1); and BC = (4, 6).

Notice that AB and AC are indeed perpendicular, meaning that the triangle has a right angle at A.

b=(-2,-3)

c=(2,3)

distance²=(x2-x1)²+(y2-y1)²

ab²=(3--2)²+(2--3)²

= 25+25

ab=√50

ac²=(3-2)²+(2-3)²

=1+1

ac=√2

bc²=(2--2)²+(3--3)²

= 16+36

bc= √52

if this triangle is a right angled triangle..

bc²=ab²+ac²(pythagorus

52=50+2

so it is a right angled triangle
