OBJECTIVE: Find the tangent of an angle and the measure of an angle using the tangent (9-9, Pp365ff) ACTIVITIES: 1) pick an angle between 0 and 90 degrees. 2) draw five(5) right triangles that include the chosen angle and are different sizes. Calculate the tangent ratio. Compare them. Use the table on page 583 to check the angle. NOTES: HOMEWORK: P606 lesson 9-9

Problem of the week (check the scoring guide) The problem of the week is due next Monday. Students are to use diagrams, charts, and tables as needed. Explain the process used to solve the problem. Be neat.

this is due on 4-24-2000!

Problem of the week: Make a scale 3 dimensional model of the "U" box where the longest side on the model is 4". (The "U" box is available in the classroom for measurement.)

Keep a journal/log of your steps and calculations. This is a 4 credit assignment - you may work with a partner (submit names By Wednesday 4-19)

  • Credit 1 - Measurement table from the original Ubox
  • Credit 2 - Scale dimension calculations (labelled)
  • Credit 3 - Scale dimension table and the actual model (paper or cardboard)
  • Credit 4 - narrative description of the process you used and/or a list of steps you took.
