SLT: I can use similarity to define trigonometric ratios as properties of angles in a right triangle.
Opening Problems:
 Two sides of a right triangle have side lengths 9 cm and 15 cm. What is the length of the third side of this triangle? (Hint: There are two different solutions to this problem).
 In a right triangle, there is a 40° angle. The length of the hypotenuse is 20 cm. Find the length of each leg of this triangle.
On Monday, we checked our theoretical values from this chart:
Then we started to fill in the “Fascinating Chart”.
Now, WORK TIME:

The Similar Triangles Project is due by this Friday.

Problem Set 3 is due by Thursday at 3:30 pm.

Delta Math — practice using the trigonometric ratios.
Mr. Dunseith, Mr. Martz, and Mr. Simonelli will be at HelpDesks.
