Question

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.

Answer 1

hmmm I'm not sure if this would be the best method, but try this:
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
