Students were given 3 colored "special" right triangles. Given the hypotenuse had a length of 1 unit, they were asked to use any geometry they learned to find the exact value of each missing side of the triangle. Eventually, students used the Pythagoren theorem as well as SOH-CAH-TOA and even combining the two 30 -60-90 triangle to create 1 isosceles triangle to find missing side lengths. We discussed how to use the special ratio to find the legs of a right isosceles if the hypotenuse was a length of 1 unit.
Student were also given a paper plate that was folded in half 3 times to create 8 sections. We mentioned this was a perfect example of exponential growth! Then we labeled all the angles present and found their corresponding coordinate values.
HW: Complete the Rotations and Angles Terminology packet. We will finish the unit circle tomorrow.
