Schedule for week of 10/1: Unit 3 - Right Triangles
Monday - Pythagorean Theorem; labeling sides in a right triangle; trig ratios
Tuesday - Solving for a side in a right triangle given an acute angle and one side length
Wednesday - Solving for an acute angle in a right triangle give two side lengths
Thursday - Angles of elevation and depression
Friday - Sin and cos of acute angles; Word problems with special triangles (30-60-90 and 45-45-90 right triangles)
Study for your quiz tomorrow. Please complete your Volume Quiz Review that you received in class today. Below are the answers:
7. A & D
12. radius = 12
13. a & b
Below are two videos explaining the Volume Quiz Review problems. The first video explains questions #1 - 13. The 2nd video explains questions #14 - 20.
Below is a quick video to complete the rest of the notes we took in class today. Homework is to complete the 12 problems in the packet you received in class today.
Homework tonight is to complete your packet on volume for prisms & pyramids. Please refer to the notes we took in class if you need help. Below is a video reviewing cross sections of cylinders, cones and pyramids that we explored today in class using playdough and dental floss.
Please watch the video below that explains naming prisms & Cavalieri's Principle. Cavalieri's Principle: if the area of the cross sections (bases) of two solids are the same and the heights are the same, then the volumes are the same.
Below are videos where I explain your homework problems.
