Question

Show that the points A-(6,2), B(1, 2) and C(6, 3) are the vertices of a scalene triangle​

Answer 1

Answer:

AB=

(6−5)

2

+(4+2)

2

=

37

AC=

(6−7)

2

+(4+2)

2

=

37

AB=AC

So, △ABC is isosceles.

Let D be the mid-point of BC. Then, coordinates of D are (

5+7

,

−2−2

) i.e., (6,−2).

Therefore,

AD=

(6−6)

2

+(4+2)

2

=

36

=6
