- In the accompanying figure, m2=68, m8=112, and m9=110. a.Which lines r and s OR l and m must be parallel? ___________ b Which pair of lines r and s OR l and m cannot be parallel? ___________arrow_forwardIn ABC,mCAB=80,mACB=60,andABC=40. With the angle bisectors as shown, which line segment is longer? a AE or EC? b CD or DB? c AF or FB?arrow_forwarda What is the general name of the point of concurrence for the three perpendicular bisectors of the sides of a triangle? b What is the general name of the point of concurrence for the three medians of a triangle?arrow_forward
- In ABC,AC=5.3,BC=7.2 and BA=6.7. With angle bisectors as shown, which line segment is longer? a AE or EC? b CD or DB? c AF or FB?arrow_forwardIn ABC, M and N are midpoints of AC and BC, respectively. If AB=12.36, how long is MN?arrow_forwardIn concave quadrilateral ABCD, the angle at A measures 40. ABD is isosceles, BC bisects ABD, and DC bisects ADB. What are the measures of ABC, ADC, and 1?arrow_forward
- In triangle ABC, line t is drawn through vertex A in such a way that tBC. aWhich pairs of s are ? bWhat is the sum of m1, m4, and m5 ? cWhat is the sum of measures of the s of ABC ?arrow_forwardA line segment joins the midpoints of two opposite sides of a rectangle as shown. What can you conclude regarding MN,AB,DCandMN,AB,DC?arrow_forwardA compass was used to mark off three congruent segment, AB, BC, and CD. Thus, AD has been trisected at points B and C. If AD=32.7, how long is AB?arrow_forward
- In trapezoid RSTV, RVST,mSRV=90, and M and N are midpoints of the nonparallel sides. a What type of triangle is RMN? b If ST = 13, RV = 17 and RS = 16, How long is RN? c What type of triangle is RVN? Hint: Use lengths of sides found in part b.arrow_forwardGeneralize your findings in Exercise 33. 33. Can you use the construction for the midpoint of a segment to divide a line segment into a three congruent parts? c six congruent parts? b four congruent parts? d eight congruent parts?arrow_forwardIn quadrilateral RSTU, RSST and UT diagonal RT. If RS=6, ST= 8, and RU = 15, determine UT.arrow_forward
