6. How many triangles are there with vertices from the points shown below?
Note, we are not allowing degenerate triangles - ones with all three vertices
on the same line, but we do allow non-right triangles. Explain why your
answer is correct.
v Hint
Solution
........
If you pick any three points, you can get a triangle, unless those three
points are all on the x-axis or on the y-axis. There are other ways to start
this as well, and any correct method should give the same answer.
