SLT: I can use similarity to define trigonometric ratios as properties of the angles in a triangle.
Opener: Two sides of a right triangle have lengths of 9 cm and 15 cm. What is the length of the third side of this triangle? (There are two different solutions to this problem.)
Notes: How can you know if your theoretical values are accurate? Tiben explains.
The Similar Triangles Project is due by Friday
Problem Set #3 is due on Thursday at 3:30 pm
