1. The problem statement, all variables and given/known data If A, B, C, D are 4 points in a plane, then find ALL correct statements if AB=BC+CD A. AB is parallel to BD B. AB+BC=CD C. AB=BD D. AB−BC=BD E. none of the above [Note: The answer could be more than one option] 2. Relevant equations None 3. The attempt at a solution I'm not quite sure how to do this question, even though it seems easy. I'm thinking option C and D but it's wrong. I'm pretty much doing guess work here because my instructor didn't explain it. Can I get some help here? Thanks in advance.
