As we build on our knowledge of trigonometry, we will review special right triangles as well as degree and radian measure.

Using the Special Right Triangles Explore, move the sliders to investigate different properties of the sides of the 45-45-90 special right triangle and the 30-60-90 special right triangle.

While investigating each triangle, what do you notice about the sides? What do you notice about the hypotenuse?

At the end of this lesson, student will be able to:

  • Understand radian measure of an angle as the length of the arc on the unit circle (ALCOS 37)
  • Understand special right triangles
