Answer 1

a right triangle
means there is a 90 degree angle
this means there should be a pair of perpendicular line segments that intercept where this 90 degree angle happens

Answer 2

see which pair of line segments has opposite reciprocal slopes

Answer 3

find the slope of AB
find the slope BC
find the slope of CA

Answer 4

ok hold on

Answer 5

if know such pair exist then this is not a right triangle

Answer 6

no (not know) :p

Answer 7

have you found the slopes of the three line segments?
when you have just drop them down here so we can look at it together if you want

Answer 8

its gona be solved using this ???
