No, It is impossible for a triangle to have 2 right angles. We know that a triangle consists of 3 sides and the sum of interior angles of the triangle, sums up to 180°. Consider, if a triangle has two right angles (90 degrees), then the third angle will have to be 0 degrees which means the third side will overlap with another side of the triangle. Hence, a triangle with 2 right angles is not possible.
