Graph the points. What do you get?

anonymous · Answer

Calculate AB, BC and CA.
If, any two are equal then it is an isosceles triangle.

anonymous · Answer

Hint use distance formula

paki · Answer

u have 3 sides AB,BC,CA to check if its isoceles.. find the lenght of the three side and find if u have 2 matches... to check if its right find the dot product 3 times when its zero that mean its right... 
AB.AC
BC.BA
CA.CB
|AB|=sqrt 130 
|BC|=sqrt 130 
|CA|=sqrt 52... so here no one is zero... so its an isoceles triangle...

anonymous · Answer

AB=sqrt130
Bc=sqrt130
CA=sqrt52.
So,it is an isosceles triangle.
