From your observations, what is the sum of the measures of the interior angles of [i]any triangle? [/i]
This is the Triangle Angle Sum Theorem: The sum of the [i]interior[/i] angles of a triangle is equal to 180 degrees.
[color=#000000]From your observations, what is the sum of the measures of the exterior angles of [i]any triangle? [/i][/color]
This is the Sum of the Exterior Angles of a Triangle: The sum of the [i]exterior[/i] angles of a triangle is 360 degrees.
