COMMON SEGMENTS THEOREM
If points A, B, C, and D are collinear and arranged in that order, and AB is congruent to
CD, then AC is congruent to BD.
The Case: You are given the diagram showing two segments, AC and BD, defend the
claim that they are congruent.
The Evidence: You are shown that Points A, B, C, and D are collinear and arranged in that
order. AB is congruent to CD.
