In triangle ADB, angle ADB is a right angle because the sum of the angles in any triangle is 180 degrees, and if we know that one angle is 90 degrees, the remaining two angles must add up to 90 degrees.
Since BD = 2.4 and AD = 1.8, which suggests that AD is perpendicular to BD, making angle ADB a right angle. Therefore, triangle ADB is a right triangle.
