Final answer:
The statement 'AB=___ CBA=___ triangle' is incomplete. Without additional information, one cannot complete the statement about the triangle. If it were about completing a unit table, one would match units with their correct abbreviations.
Step-by-step explanation:
The question as stated, 'AB=___ CBA=___ triangle', is incomplete and lacks enough information to be answered definitively. Therefore, the correct response would be to indicate that the statement is incomplete. When we discuss geometrical figures like triangles, we often refer to their sides and angles with respective measurements or relations between them. Without more specific information or context, filling in the blanks is not possible. For example, AB could be the length of a side, and CBA could be the measure of an angle in a triangle, but without additional data, we cannot complete the statement.
If this were a question about filling in a unit and abbreviation table for measurements, one might need to provide typical units and their respective abbreviations. For instance, in a table with units on the right side and abbreviations on the left, one could fill missing units like meter (m), kilogram (kg), or second (s), and their corresponding abbreviations on the left.
