PLS PLS PLS help me I'm reposting this question bc no one helped me
Determine whether line segment AB is a diameter of the circle.
O Yes, Triangle CAB is congruent to triangle DAB by the SAS Congruence Theorem, so line segment BC is congruent to line segment BD. This means that line segment AB is a perpendicular bisector of line segment CD.
O Yes, The endpoints of line segment AB lie on the circle, so line segment AB is a diameter by the definition of a diameter.
O No, because line segment AB does not bisect line segment CD, line segment AB cannot be a diameter
O No, line segment AB is not perpendicular to line segment CD, so the Perpendicular Chord Bisector Theorem cannot be used to conclude that line segment AB is a diameter
