Module 4: The Right Kind Of Triangles

 

Refresher

 

If you don’t know the answers in Are You Ready?, or if you require more information, do some review of solving a right triangle and slope representations.

 

Solving a Right Triangle

  • Use the demonstration applet Right Triangle (Solve) to review how to solve right triangles. After clicking on the play button to the right, you will need to select Grades 10 to 12, and then the letter R. Scroll down the list and choose Right Triangle (Solve). Once in the applet, click on the unknown sides or angles to see some methods you could use to solve. The applet will create questions for you or you can also set up your own questions.

  • Watch the Solving a Triangle animated example to see step-by-step solutions to a problem.
