Question 457166: can you explain to me why the exterior angle of a triangle equals the sum of two interior opposite angles thanks alot Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! The sum of angles in a triangle = 180 degs
The sum of any 2 angles = 180 - the 3rd angle
--------
The exterior angle also = 180 - the interior angle
There's no "why", it just does
