Question

Show that points a(1,2) b(3,4) and c(0,1) are vertices of a scalene triangle​

Answer 1

Step-by-step explanation:

distance ab=root of (1-3)^2+(2-4)^2

=root of (-2)^2 +(-2)^2

=root of (4+4)

=root 8

distance bc=root of (3-0)^2+(4-1)^2

=root of (9+9)

=root 18

distance ca=root of (0-1)^2+(1-2)^2

=root (1+1)=root 2

distance are not equal

hence proved
