Any side of a triangle must be shorter than the other two sides added together.
The third side is between the sum and difference of the two sides
The larger the angle, the longer the side opposite to it
Exterior Angles
The angle between any side of a shape, and a line extended from the nest side. They are linear pair, which means they are supplementary (forms 180 degrees)
Exterior Angles Theorem
The measure of an exterior angle of a triangle is greater than the measure of either of its remote interior angles
The exterior angle is equal to the sum of the two remote interior angles
