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.)
Return Problem Set #1 and #2
Here’s what we discussed on Friday: How can you know if the theoretical values posted in this chart are accurate?
If you’re not sure how to check these answers, see Mr. Simonelli or Mr. Dunseith at his Helpdesk.
Work Time:

The Similar Triangles Project is due by this Friday

A Fascinating Chart is one of the items in the project checklist.


Problem Set #3 is due on Thursday at 3:30 pm
