Triangle Angle Relationships
- Jed Butler
Use the checkboxes, sliders, and buttons to control the different parts of the triangle (and to see equations that represent the relationships with the angles). If an animation stops part way, drag the slider with your pointer to finish it.
1) What patterns do you notice? 2) After the transformation what parts are still the same? 3) Can you write an equation with the angles showing how the sum up? Can you write another one? How many ways can you write an equation?
