Can a triangle with the angles of 0, 90 , and 90 be considered a triangle?
asambeis [7]

A "triangle" with the angles 0, 90, and 90 degrees cannot be considered a triangle since the two 90 degree angles make a right angle, and 0 degrees would mean a flat line. Rather it would resemble something like a straight U that is stretched sideways.
