Standards and Benchmarks Covered in this Lesson
Select and use appropriate tools; make accurate measurements using both metric and common units, and measure angles in degrees
Use proportional reasoning and indirect measurements including applications of trigonometric ratios, to measure inaccessible
distances and to determine derived measures such as density.
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.
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.
Checkpoint Pg 27
What relates the sides
of a right triangle?
How can that relationship
help us calculate the lengths unknown sides?
What relationships help
us find the side and angle measurements in any right triangle? ØIf you calculate a side given a length and an angle?
