Can someone check this for me?

Question

anonymous · Answer

Determine if triangle XYZ with coordinates X (1, 1), Y (5, 6), and Z (6, 2) is a right triangle. Use evidence to support your claim. If it is not a right triangle, what changes can be made to make it a right triangle? Be specific.

Considering this and the slopes, I think it is a right angle, but is it?

jigglypuff314 · Answer

find the slope between each point
slope of XY = ?
slope of YZ = ?
slope of XZ = ?

then see if any are perpendicular (right angles)
a perpendicular slope is the flipped opposite of each other
for example  the right angle slope of  a slope of   -4  would be  1/4

I don't think it is a right triangle

may I ask, what school do you go to?
I just saw another person ask this question recently

anonymous · Answer

I'm actually not in school anymore. I bought a bunch of review books to study from before I go to college. I've never been good with math and I want to change that.

I've also been using online study guides.
