Students explore how to use trigonometry in the aviation field.  For this aviation lesson students complete trigonometry equations that show what planes should do to land their airplanes.

Young scholars measure distances using parallax. In this math lesson, students explain how this method helped astronomers with their studies of the solar system. They determine the length of their arm using parallax and compare it with...

Looking for an easier way to do angular measurements? This page introduces you to a trick by using skinny triangles with small angles. The skinny triangles lets the astronomer assume right triangles and then they can use trigonometry to...
