Answer:
Step-by-step explanation:
Given,
A = ( -3 , 1 )
B = (1 , -2)
C = (1 , 4)
To Show :-
That these are Vertices of an Isosceles triangle.
Condition to Prove that Above points are Vertices of an Isosceles triangle :-
Show that two of it sides lengths are equal.
Solution :-
Calculating lengths of Sides :-
That is Distance b/w AB,AC,BC.
Distance formula :-
1) AB :-
= 5 units
AB = 5units
2) BC :-
= 6 units
BC = 6units
3) AC :-
= 5units
AC = 5units
Since , we showed that AB = AC .
Hence Showed.
