Homework 954: 3, 6 and58: 7, 9Page 54#3.If two Saccheri quadrilaterals have equal arms and unequal bases, prove that the onewith the greater base has smaller summit angles. (Use Ex. 2 and Theo. 39).Consider Saccheri quadrilateralsABCDandPQRS,givenBC = DA= QR = SPas shown and WLOG letPQ > AB.LocateTonPQsuchthatAB = PT,and constructTUperpendicular toPQ.
#6 Prove that two lines have a common perpendicular if there is a transversal such that thatthe sum of the two interior angles on the same side of the transversal it 180°.Let transversal t fall on lines a and b such that the sum of two interior angles on thesame side of t is 180° as illustrated. Call the intersection of lines t and a as point A and the
