Warm up on equilateral triangle and using trigonometry to find height. Reviewed, then took assessment on trigonometry basics and then worked on ACT practice.
Homework
Watch and take notes on this video: direct link
Warm up on applying special right triangles to do trig-type problems without a calculator. Passed back assessments, then did 2 application problems involving trigonometry before playing Kahoot with advanced trig problems dealing with complementary angles. Then passed out "Trigonometry Stack" and got started on it together.
Notes from board
Homework
- Work on "Trigonometry Stack" handout, will have 15 minutes to complete it in class Thurs/Fri also. ROUND TO 3 DECIMAL PLACES FOR ALL TRIG RATIOS AND SIDE LENGTHS.

Continued working on "Trigonometry Stack" problem or another dealing with how to find dimensions of an equilateral triangle given its area. Watched how trigonometry and geometry 'made the word' by looking at Eratosthenes' circumference calculation and then worked through 3 different math tasks dealing with triangle measure and trig: taco cart problem, the lost in the park problem, and the planting sod problem.
