Question

Show that the points A(-5,6), B(3,0) and C(9,8) are the vertices of an isosceles right-angled triangle. Calculate its area. 

Answer 1

Let the given points be A(-5,6), B(3,0) and C(9,8) .

Therefore, the points A(-5,6), B(3,0) and C(9,8) are the vertices of an isosceles right angled triangle.
