Jason drew a triangle to explain the Triangle Sum Theorem and labeled the angles 1, 2, and 3 He tore each angle off the triangle so he could move the three angles around.

What should Jason do next to explain the Triangle Sum Theorem?

Jason should line up the angles next to each other as adjacent angles to show that the 3 angles together form a straight angle.

Jason should create a new triangle by moving the angles closer together to show that the 3 angles can create other triangles.

Jason should fold each angle in half to show each angle with one half of the measure it had in the triangle.

Jason should stack the angles on top of each other to show that the 3 angles have the same measures.
