Students will attempt to determine the length of a side and the measure of an angle for a non-right triangle using the tools they already have (SOH CAH TOA, Pythagorean theorem, angle sum of a triangle, Sine Law etc). Students will complete BLM 7.3.1. Once they have a solution, they will share their answer with their partner.
“Ask” the Right Question to Get the Right Answer-Teacher Notes
Using the Pythagorean Theorem. Everyone can say but not everyone can use it to answer questions. What did Pythagorus really say and how can you use a calculator to do the work? Pythagorus said that similar figures attached to the sides of a right triangle (we use squares because they are easy) have a particular relationship. The sum of the areas of the two smaller ones equals the area of the ...
