Lesson 7-5: Right Triangles


Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

Objective:

The student will be able to solve right triangles using the basic trig functions.

  1. Drag the red point around the axes.
  2. Instead of reading the angle in standard position, this gives you the bearing of the angle. This will be useful when you have to solve word problems involving bearing. Make sure you can communicate an angle’s bearing correctly!
