A triangle can never have three right angles
a right triangle has one right angle and two acute angles
In a right angled triangle the two other angles are acute.
In a right angled triangle the two other angles are acute.
A triangle can have at most one right angle.

As there are 180 degrees in every triangle, and you have to have three angles, you can only have one right angle.

a triangle can have only one right angle because the sum of all the three angles of a triangle has to be 180. so if there are more than one right angles, the sum of the angles will exceed 180 and hence the plane figure will no longer be a triangle

None. If there was a right angle then it would not be called an acute triangle.
None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
