Triangle Sum Conjecture
Instructions
Click and drag the vertices of the triangle to form different types of triangles. For each triangle you make, add up the values of the angles in the triangle and record this value on a piece of paper.
1. Make an acute triangle.
2. Make an obtuse triangle.
3. Make a right triangle.
Triangle Sum Conjecture
Write a conjecture for your observations about the sum of the angles in a given triangle.
