Trig Ratios animated

Two different triangles are animated.  Show your class this animation and simply ask:
  • What do you notice?
  • What do you wonder?




After some conversations show them this one, with the side lengths being shown and ask again:

  • What do you notice?
  • What do you wonder?


Lastly, show them this image and ask them "How could we analyze this?"


  Some possible routes:

  • Prove the sides hold true for Pythagorean theorem
  • What angle(s) would be in the triangle?
  • How are these 2 triangles similar?  How are they different?
