Given: AB is congruent to DE, and BC is congruent to CD. Prove: Ad is congruent to BE. Points A,B,C,D,E are all on one ling segment all the same distance from each other. Thank you for the help! Ans: Given that A,B,C,D,E are all in the same line AD = AB + BC + CD -> since all are part of the same line Similarly, BE = BC + CD + DE ---> since they are in the same line = BC + CD + AB (since AB is congruent to DE) = AB + BC + CD (rearranging the terms) From the above 2 equations, AD = BE As simple as that :) Let me know if it is not clear.
