Standards and Benchmarks Covered in this Lesson

          II,3,1: Select and use appropriate tools; make accurate measurements using both metric and common units, and measure angles in degrees and radians.

          II,3,5: Use proportional reasoning and indirect measurements including applications of trigonometric ratios, to measure inaccessible distances and to determine derived measures such as density.

Introduction

Anticipatory Set: Warm up cartoon and Pythagorean Theorem review.

Objectives: After students measured the lengths of triangles and we briefly discussed the Pythagorean Theorem yesterday and going over the warm-up today, students will be able to complete the investigation they began yesterday.

Investigation

Students will finish up investigation 1 of lesson 2 today.  I will guide them to a deeper understanding of the content by giving multiple representations of the content and by asking carefully designed questions.

Conclusion

v    Checkpoint Pg 27

Ø     What relates the sides of a right triangle?

Ø     How can that relationship help us calculate the lengths unknown sides?

Ø     What relationships help us find the side and angle measurements in any right triangle?
