Is it possivle to show that <IJG is congruent to <IHK? A. Yes; IG = IK by the segment addition postulate, and <I = <I by the reflexive property of congruence, so IJG = ihk by SAS. Therefor <IGJ = <IHK by CPCTC. B. Yes; IG = IK by the angle addition postulate, and <I = <I by the symmetric property of congruence, so IJG = ihk by SAS. Therefor <IGJ = <IHK by CPCTC. C. No; we cannot prove that IJG = IHK, so we cannot use CPCTC to show that <IJG = <IHK. D. No; IJG = IHK, but <IJG is not corresponding angle to <IHK, so they cannot be proven congruent by CPCTC.
