Triangle Sum Theorem
To investigate: Click and drag the vertices of the triangle. Complete the following steps/questions. 1) Click and drag the vertices forming an acute triangle. 2) Record the interior angle measures of the triangle. 3) Write an equation relating the interior angle measure. 4) Repeat steps 2 and 3 for a right and obtuse triangle. 5) What do you observe about the triangle's 3 interior angles? 6) Does the Triangle Sum Theorem hold true for each case? Why or why not?
