<PRE><B>Question 359934</B>
When the lines are parallel:


Interior Angles on the Same Side of the Transversal


(measures are supplementary)


Their &quot;name&quot; is simply a description of where the angles are located.


Interiors on the same side of the transversal make the following possible:


m&lt;1 + m&lt;2 = 180 degrees.


m&lt;3 + m&lt;4 = 180 degrees.


The conclusion is m&lt;1 + m&lt;2 = m&lt;3 + m&lt;4.
