Answer the question.John goes to a building and stands 100 feet away. He measures the angle of elevation to the top of the building as 37°. He also measures the angle of elevation 100 feet away from a different building. It is the same. He concludes that the buildings are the same height. Is he right? Explain.
What will be an ideal response?
John is right. The triangle formed by John's feet, the base of the first building, and the top of the first building is congruent to the triangle formed by John's feet, the base of the second building, and the top of the second building. They are congruent by ASA.
