I'll give u discuss the locations of the angle of depression and angle of elevation of a right triangle. which one is inside the right triangle? which one is outside? 2. discuss the geometry concepts that explain why the angle of depression is congruent to the angle of elevation in a right triangle. how do parallel lines and a transversal ?

The angle of elevation of an object as seen by an observer is the angle between the horizontal and the line from the object to the observer's eye (the line of sight). This angle is seen outside of the triangle. If the object is below the level of the observer, then the angle between the horizontal and the observer's line of sight is called the angle of depression. This angle is seen inside the triangle. The angle of depression equals the angle of elevation because they from alternate interior angles or congruent angles located on different parallel lines cut by a transversal line.
