1, Which one of the following statement is true? A Quadrilateral is a four-side geometric figure bounded by line segment. B. Diagonal is a line segment that connects two opposite vertices. C. Adjacent sides are sides of geometric figure that have a common end point D. All of the above.
I'm not sure about A but if both b and c are correct that means A must be as well. If you need a real explanation I'll be happy to explain but I'm tired.
