网考网解析：
Use TACTIC 4, Chapter 12. Could the columns be equal Could c = 5 Sure, if this is a 3-4-5 right triangle. Must c = 5 No; if the triangle is not a right triangle, c could be less than or more than 5. Neither column is always greater, and the columns are not always equal (D). (Note: Since the figure may not be drawn to scale, do not assume that the triangle has a right angle.)
