The three angles inside any triangle always add up to 180 degrees.
If one of them is 90 degrees, then the triangle is a right triangle.

No, because a triangle can only have 180 degrees max, and a right angle has 90 degrees, that means that if there are 2 right angles in a triangle, there will already be 180 degrees, meaning that it will be impossible to make a triangle.
No, a right angled triangle needs an angle that is 90 degrees. Here, all the angles don't even make up 180 degrees.
all internal angles in a triangle should add up to 180. If you already have an angle of 63 degrees and a right angle (90 degrees) the the other angle must be 27 degrees. 180 - (63 + 90) equals 27
There are 180 degrees total in a triangle. A right angle is 90 degrees, so two would already reach 180. (90+90=180) You need three angles to make a triangle, so if there are already 180 degrees, you can't have a third angle.
No. All three angles inside a triangle add up to 180 degrees. If a triangle had two right angles, then those two angles alone would add up to 180 degrees, and there would be no more degrees left to make the third angle with.
