Class Agenda #6: SUPERNOVAS!

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?

The SUPERNOVAS came up with these theoretical values for their rectangle ratio on 2/6/13.  Were they right?

If you’re not sure how to check these answers, see Mr. Simonelli or Mr. Dunseith at his Helpdesk.

Work Time:

  1. The Similar Triangles Project is due by this Friday

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

  3. Delta Math – practice using the trigonometric ratios
