Given: RT SU Prove: RS = TU R S T U Plan: Use the definition of congruent segments to write the given information in terms of lengths. Next use the Segment Addition Postulate to write RT in terms of RS + ST and SU as ST + TU. Substitute those into the given information and use the Subtraction Property of quality to eliminate ST and leave RS = TU. 2. Given: m 5 = 47 Prove: m 6 = U T S Plan: Use the Linear Pair Theorem to show that 5 and 6 are supplementary. Then use the definition of supplementary angles to show that their measures add up to 180. Finally use substitution and then subtraction to arrive at the Prove statement.. Given: AB = B B = B Prove: B is the midpoint of A A B Plan: Write the Given information and use the transitive property to show that AB=B. Then use the definition of congruence to show that the segments are congruent and the definition of midpoint to finish the proof. 4. Given: l bisects N at P Prove: P = PN P l Plan: Use the definition of bisect to show the two smaller segments are congruent. Then use the definition of congruence to show that their lengths are equal. N 5. Given: 1 and 2 are supplementary; 1 Prove: and 2 are supplementary 1 2 Plan: Use the definition of supplementary angles and congruent angles to write the given information in terms of angle measures. Next use substitution to show that m + m 2 = 180. Then use the definition of supplementary angles for the conclusion.
