90 degrees
acute, obtuse and right angles
A triangle can only have a maximum of 1 right angle. The total degrees of all the angles of a triangle adds up to exactly 180. Since a triangle must have exactly three angles, it is not possible for the triangle to have more than one angle that is 90 degrees.
The third angle must be 90 degrees so it's a right-angled triangle
0. A triangle can either have no right angles or it can have 1 (in which case it is a right angle triangle).

Right angled triangle
Yes
The fewest number of right angles in a triangle is zero.
the number of obtuse angle in a right triangle is zer0
A triangle can have at most one right angle.
A triangle cannot have two right angles. Triangles angles should add up to 180. There are three angles. If there are 2 right angles, there would be no third angle, therefore, no triangle. XD

One, if there were anymore, it would have more than three sides.
