Which of the following can be used to describe the triangle with the vertices listed below?
F(1, 2), G(10, 2), H(12, 11)
I. acute
II. obtuse
III. right
IV. scalene
V. isosceles
VI. equilateral
Please help!!! Explain.

F and G lie on the same horizontal line.
H lies a bit to the left of G, and well below it.
That makes angle FGH obtuse.
If only one answer may be chosen, then (II)
FG=9
FH=17.02
GH=13.15
So, (IV) is also true 
I had answered that same question for you yesterday.
