-- The two sides of a right <u>angle</u> intersect and make the angle.
So do the sides of any other angle. So they can't be parallel.
-- No two sides of a right <u>triangle</u> ... or any other triangle ...can be parallel.
If they are three consecutive integers then they are:
k, k+1, and k+2 and the sum would then be:
s=k+k+1+k+2
s=3k+3
no solutions → C
The 2 given lines are parallel and never intersect thus no solution
