text: An exterior angle of a triangle is an angle that is a linear pair (and hence supplementary) to an interior angle.
text: The other important theorem we need to use here is that the interior and exterior angles are supplementary angles: in other words, their sum is 180 degrees.
text: The interior and exterior angles of a polygon form a linear pair and are therefore supplementary with a sum of #180^o# ?
text: Adjacent angles are supplementary.
text: that you can also see that an interior angle and its associated exterior angle are supplementary ...
text: At each vertex of a polygon, an exterior angle may be formed by extending one side of the polygon so that the interior and exterior angles at that vertex are supplementary (add up to 180).
text: We now know that interior and exterior angles are supplementary (add up to 180) at each vertex, so the measure of each exterior angle is 180 - 120 = 60.
text: Each exterior angle is supplementary to this and therefore must have measure
text: A rhombus therefore has all of the properties of a parallelogram: for example, opposite sides are parallel; adjacent angles are supplementary; the two diagonals bisect one another; any line through the midpoint bisects the area; and the sum of the squares of the sides equals the sum of the squares of the diagonals (the parallelogram law).
