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.

A=90, B=53.13, C=36.87, and the sum is 180

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
