Move the pink angle to point A, and move the orange angle to H.[br]What is their new degree?
Move the pink angle to point B and leave the orange angle at H.[br]What is their new degree?
If the pink angle is at point C, and the orange angle is at point H, what is the angle of elevation?
Why does the orange angle degree change when moving the pink angle?
The total degree of a triangle is 180 degrees. If we move the pink angle to a smaller degree, the orange angle (along with the 90 degrees) must add up to 180 degrees.
