If two adjacent sides of a parallelogram are equal in length, then it will be a rhombus because all sides of it will be equal
From the given picture we can see a parallelogram with 4 equal sides, then
The best name describes it is a rhombus
In the rhombus
Every 2 adjacent angles are supplementary (their sum = 180 degrees)
Then the angle that measures 116 degrees and angles 1 and 2 are supplementary because they are adjacent angles
Subtract 116 from both sides
Since the diagonal of the rhombus bisects the vertices' angles
Since the opposite angles in the rhombus are equal in measure, then
Divide the sum of <1 and <2 by 2 to find the measure of each angle
The measure of the numbered angles is 32 degrees
