The sum of the internal angles of a triangle is 180º. If B is a right angle it has 90º, so there are only 90º left for the other two angles, meaning that they cannot be right!
A right angle triangle has a right angle and two acute angles that all add up to 180 degrees.
A triangle can have only one right angle (90o). Such a triangle is called a right triangle.
True
A triangle has only 1 right angle. It only has one side that can possibly be a right angle. The type of triangle varies.
A right angle triangle
1. A triangle is a right triangle if and only if it has a right angle. 2. A triangle has a right angle if and only if it is a right triangle.

This is one of those instances where US terminology causes totally unnecessary confusion. The original description of a triangle containing a 90o angle is "a right-angled triangle".
Sum of all angles at vertices in a triangle is 180. Right angle means 90 Degree. A triangle can have only one Right angle.
