View the triangle. Can you see the relationship between the exterior angle to a given angle in a triangle and the other angles in a triangle? Let's see if we can help. [br]1. Use the slider to rotate the triangle 180 degrees. [br]2. Now, use the red point below to translate the triangle over and line up the blue points.[br]3. How are the angles not adjacent to the exterior angle (green and purple) related to the exterior angle?[br]4. Use the red point to change the angle of the triangle and see if this is true for all triangles. [br]5. Write an equation for the relationship between the non-adjacent interior angles of a triangle and the exterior angle.
