Question

Show that the points (14,10),(11,13)and (2,-2) are the vertices of a right angle triangle tell this solution

Answer 1

Answer:

let A(14,10), B(11,13), C(2,-2)

AB^2=(14-11)^2+(10-13)^2

AB^2= 9+9=18

BC^2=(11-2)^2+(13+2)^2

BC^2=81+225=306

CA^2=(14-2)^2+(10+2)^2

CA^2=144+144=288

AB^2+CA^2=BC^2
