InCA Final Trigonometry Project – Trig in My World

I am excited to announce our final project for Unit 6, about right and non-right triangle trigonometry! It is called [drumroll]

Trigonometry in My World

The expectations of the project are simple (full details for this project are here)

  1. Find two triangles in your world and take a picture. They can be in your room, somewhere in your home or apartment, in a nearby park, or somewhere you go frequently.
    • Neither triangle can be a right triangle or an equilateral triangle, and at most one can be isosceles
  2. Measure the side lengths of the triangle, either the real physical one or your picture.
  3. Use the Law of Cosines, find one angle measurement for the triangle
  4. Use the Law of Sines to find another angle measurement
  5. Find the third angle by using the fact that all three angles add to 180°
  6. Use the Sine Formula for Area to find the area of the triangle.

You will create a Google Slides Presentation with two slides, one for each triangle. On each slide, upload your picture of the triangle and either type your math work or upload clear photos of handwritten mathematical work.

Your Google Slides are due on Monday, June 8. I’ll be using this rubric to grade this project.

Questions? Please email me to ask and/or sign up for or drop in during an Office Hours session!

InCA Lesson 6.4 – Law of Sines Part 2 – Ambiguous Case

As you are aware by now, schools have been shut down for the remainder of the school year. This means that we will be continuing with this distance learning model until June. I don’t currently know exactly when the last date of instruction will be, but will be sure to let you know as soon as I find out.

I am shifting our schedule slightly for the remainder of the academic year. The first part of our lesson will be posted on Tuesday, with the video and Problem Set 1 due on Friday. The Desmos assignment and Problem Set 2 will be due the following Tuesday. Full details of the new schedule are here.

Completing this activity is due on Tuesday, 5/12 at 2:00 pm, and will be worth 10 points.


Friday Update

Tuesday’s video+notes and Problem Set 1 are due at 2:00 on Friday, 5/8.

There is another Office Hours session today. Sign up for an Office Hours session to ask questions and get extra help.

Tuesday’s Notes + Video and Problem Set 1 are due at 2:00 today (4 points each). Send a picture or scan of your completed work (I recommend the app TurboScan) to bkirk@icsd.k12.ny.us

PROBLEM SET 2 for this week can be found here (as a Google Form) or here (as a PDF download). Submit your answers to this and to your Desmos activity by Tuesday, 5/12 at 2:00 pm. You must obtain a target score of 4 out of 6 points to earn credit for this assignment, but your grade will not be based on how many points you get (just whether or not you made that cutoff). If you submit via the Google Form, the form will tell you which answers were right or wrong, however once you finish the problem set, I will need to access your responses and evaluate for explanations to finalize your score.

Reaching the target score on this assignment worth 8 points in SchoolTool. Submitting the work but not reaching the target score is worth 6 points.
