The triangle you described has angles measuring 79°, 11°, and 90°. Since one of the angles is 90°, this indicates that the triangle is a right triangle. In addition, the other two angles are acute (less than 90°), but the key characteristic that defines it is the presence of the right angle. Thus, the triangle is a right triangle.
