Resource:
GeoGebra Slider that shows the sum of the interior angles of a triangle equal 180 degrees
Slider shows that all 3 angles in a triangle add to 180 degrees. Can be used to classify triangles as acute, obtuse, right, scalene, isosceles, equilateral. Can be used to analyze angle side relationships.
