Answer 1

Answer:

mrk me as brainliest nd thanks me plsss

Step-by-step explanation:

A=(1,5) , B=(2,3)

So AB= square root over 2-1 + 3-5

=square root over -1

C=(-2-1)

So BC=square root over -2-2 + -1-3

= square root over -8

=2 root 2.

Therefore AB+BC= square root of -1-8

=square root over-9

=-3.

So in order to verify whether AB+BC=AC

AC =square root over -2-1+-1-5

=square root over-9

=-3.

THEREFORE IT PROVES THAT AB+BC=AC AND THE POINTS HAVE BECOME COLLINEAR TO EACH OTHER .Proved
