No, because a triangle must have an obtuse angle.

Yes, because 90 + 90 = 180.
Yes, because 90 plus 90 equals 180 .
Yes, because it would be a right triangle.
Yes, because it would be a right triangle.
No, because there needs to be a third angle

No, because a triangle by definition has three angles that must add up to 180 degrees. If two of the angles are right angles (90 degrees each), then the third angle would have to be 0 degrees in order for the sum to be 180 degrees. Therefore, a triangle cannot have two right angles.

No, a triangle cannot have two right angles. According to the definition of a triangle, it is a polygon with three sides and three angles. The sum of the interior angles of a triangle is always 180 degrees. If two angles are already right angles (90 degrees each), there is no room for a third angle, and thus it cannot be a triangle.
