Visualizing Triangle Inequalities
- Roland Richter
This worksheet shows how to construct a triangle when the side lenghts a, b, and c are known. Step through the construction by using the arrow keys below.
- What can happen if you change the side lenghts a, b, or c? Identify at least three different cases. Hint: You can change the side lenghts by moving the slider values.
- Which conditions must be fulfilled such that these cases can happen? Write down conditions in your own words, or by menas of a formula.
