Triangle Exterior Angle

[color=#000000]In the app below, an [b]exterior angle of a triangle[/b] is shown.[br]The 2 colored angles[/color][color=#000000] are referred to as its [/color][i]remote interior angles. [/i]
Interact with this app for a few minutes. LARGE POINTS are moveable.
[color=#000000]What can we conclude about the measure of an exterior angle when we compare it to its remote interior angles? Explain. [/color]
What other theorem is readily made obvious here?
