Question

Is △TVS scalene, isosceles, or equilateral? The vertices are T(1, 1), V(9, 2) and S(5, 8).

Answer 1

if you calculate the lengths of the sides you'll get your answer
eg
length of Side TV = sqrt((1-9)^2 + (1-2)^2) = sqrt65
do similar thing for VS and ST

Answer 2

Thank You, I dont undertsand which triangle it would be though.

Answer 3

VS works out to sqrt52 and ST to sqrt65

so its a triangle with 2 sides equal
which is that?

Answer 4

isosceles

Answer 5

right

Answer 6

length of a line between two points is

sqrt[(x2-x1)^2 + (y2-y1)^2]
