A triangle can not contain two right angles. This is because:
Because 90 + 90 = 180, that leaves the remaining angle in the triangle at 0 degrees, making the shape not a triangle but a line segment.

A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
No. It is not possible to have two right angles.
If two angles are right angles, their sum is 90o + 90o = 180o leaving nothing for the third angle. There is no triangle with two right angles.
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
