Example Question #11 : How To Find An Angle In A Rhombus
A rhombus has two interior angles each with a measurement of 
First, consider that the sum total of the four interior angles in any rhombus must equal 
One way to approach this problem is to realize that each of the remaining two angles must have the same measurement, and that each will be supplementary angles with 
Example Question #12 : How To Find An Angle In A Rhombus
A rhombus has two interior angles each with a measurement of 
A rhombus must have two sets of equivalent opposite interior angles, and a rhombus must have two sets of adjacent interior angles. The adjacent interior angles must be supplementary—meaning they have a sum total of 
One way to approach this problem is to realize that each of the remaining two angles must have the same measurement, and that each will be supplementary angles with 
Example Question #13 : How To Find An Angle In A Rhombus
A rhombus has two interior angles each with a measurement of 
To solve this problem, consider that the sum total of the four interior angles in any rhombus must equal 
Since this problem provides the measurement for two of the interior angles, find the sum of those two angles. Then subtract that sum from 
The solution is:
Note: this means that each of the two remaining angles must have a measurement of
