Given that m∠RQU is supplementary to m∠SUQ, why is US || PR? http://secure.starssuite.com/files/Geo2010/Geom_05S_Fig01.jpg

OpenStudy (aum):

PR is a straight line and therefore, m∠RQU and m∠PQU are supplemenatry. We are given m∠RQU andm∠SUQ are supplemenatry. Therefore, m∠PQU = m∠SUQ which implies US || PR because m∠PQU and m∠SUQ are alternate interior angles.
