Given the midpoint(M)and either endpoint ofAB, find the other endpoint.
14.A(− 1 , 2 )andM( 3 , 6 )
15.B(− 10 ,− 7 )andM(− 2 , 1 )
16.Error AnalysisErica is looking at a geometric figure and trying to determine which parts are congruent. She
wroteAB=CD. Is this correct? Why or why not?
17.Construction ChallengeUse construction tools and the constructions you have learned in this section to
construct two 2 in segments that bisect each other. Now connect all four endpoints with segments. What
figure have you constructed?
