Just “Tri” Living Without “Trigonometry”
of a right triangle, given an angle and a length of a side.
This project is designed to help you fully grasp the concept of using trigonometry to solve
problems. This includes finding the length of a missing side or a missing angle of a right triangle,
identifying these problems in everyday life, drawing them, calculating their values, and weaving it
all into an interesting, amusing, or creative story!
Your task is to develop a story involving the missing angle or missing side of a right triangle. To
support your story, you will need to use a recent picture of yourself. You will need to include all
formulas and all of the steps required to come up with your answer for your story.
Requirements
For this project you MUST complete two drafts to get full credit:
• Concept idea (rough draft):
o Rough draft of story, picture, and calculations
o Can include color, but not required
o Concept idea will help to ensure appropriateness, accurateness, and clarity of
thought for the final draft
o This WILL NOT be collected, just signed or stamped for approval
o This draft is for your benefit to insure you have done the project correctly
• Final Draft must include:
o Imaginative
o Appropriate subject
o Must be a trigonometry problem (finding a missing side or angle)
o The story MUST be more than one sentence. It must be a STORY.
o An actual picture to illustrate your story
▪ The picture must be visible and clearly definable
▪ The picture must be appropriate to the story and to class rules and
expectations ☺
o A diagram of the right triangle to solve the problem
▪ Provides a clear representation of the problem
▪ Include realistic measurements
▪ Include units
▪ Neat (MUST use straight edge, or computer representation)
▪ It can be incorporated into the picture but it must be clear legible and visible
▪ It must be a right triangle, and labeled with a right angle mark
o Calculations
▪ Show formulas you used
▪ Show all steps
▪ Include units in your answer
o An appealing presentation
▪ Professional look
▪ Story should be typed or neatly printed
▪ Colorful
▪ Appropriate subject
▪ Title, size limit: 8½ x 11 inches
