and complete each step below. If you need help, follow these instructions for using GeoGebra.

Question 1

Record the measures of the interior angles of ∆ABC (αβ, and γ), and find their sum.

Question 2

Move vertices AB, and C to create a triangle of your choice. Record the measures of the interior angles αβ, and γ for three different triangles. Then find the sum of the angle measures for each triangle.

Question 3

How does the sum of the interior angles change as you move the vertices of ∆ABC to create a triangle of your choice?
