Answer:
Step-by-step explanation:
(8,4),(5,7),(-1,1)
By using distance formula,
AB =√(x2-x1)^+(y2-y1)^
=√(5-8)^+(7-4)^
=√17+33
=√50
=2√25 sq. Units
BC=√(x2-x1)^+(y2-y1)^
=√{(-1)-5}^+(1-7)^
=√72
=2√36 sq. Units
CA=√(x2-x1)^+(y2-y1)^
=√{(-1)-8}^+(1-4)^
=√81+9
=2√45 sq. Units
Therefore, given pts.are not the vertices of right angled triangle.
