Hi, my name is Stefan. Today, I'm going to be speaking on math projects involving triangles. A good project I like to do is, let students calculate the height of the buildings and different floors using the angle of elevation method for a triangle. Let's say we have a building, there's floor number one, floor number two and floor number three. We know there's a right triangle here. When calculating the height, all I have to do is, if I'm given this angle theta, wants to define the angle. We know that the tangent of theta equals the opposite over adjacent. And this distance we know. So, it's a fun way to get students to calculate he height. I'll have them do the first floor, the second floor and then, the third floor. And the height is always going to be equal to this distance times tangent of theta. And this is a good math project for students to do, involving triangles.
