Segment And Angle Proofs Worksheet Answer Key

Segment And Angle Proofs Worksheet Answer Key In a proof you make one statement at a time until you reach the conclusion Because you make statements based on facts you are using deductive reasoning Usually the fi rst statement and reason pair you write is given information Proof of the Symmetric Property of Angle Congruence Given 1 2

PROPERTIES AND PROOFS OF SEGMENTS AND ANGLES In this unit you will extend your knowledge of a logical procedure for verifying geometric relationships You will analyze conjectures and verify conclusions You will use definitions properties postulates and theorems to verify steps in proofs 5 2 I can prove segment and angle relationships 1 Given B is the midpoint of AC Prove AB BC 2 Given AD is the bisector of BAC D Prove m BAD m CAD 3 Given D is in the interior of BAC D Prove m BAD m DAC m BAC 4 Given m A m B 90 176 Prove m C m B 90 176 A C 5 Given lt 1 and lt 2 form a straight angle
