You will use the GeoGebra geometry tool to study the interior angles of triangles. Go to interior angles of triangles, 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 (α, β, and γ), and find their sum.

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x? y? z? , with vertices x? (4, -2), y? (4, -3), and z? (1, -4). the type of transformation that triangle xyz undergoes is a . triangle x? y? z? then undergoes a transformation to form triangle x? y? z? , with vertices x? (4, 2), y? (4, 3), and z? (1, 4). the type of transformation that triangle x? y? z? undergoes is a .
