Answer 1

The pair of trimming methods that require the user to first select two bounding entities or a face and then choose the entities to be trimmed are Boolean Trim and Offset Trim.

Step-by-step explanation:

The pair of trimming methods that require the user to first select two bounding entities or a face and then choose the entities to be trimmed are called Boolean Trim and Offset Trim.

In Boolean Trim, the user selects two entities (lines, arcs, or circles) or a face and then selects the entities to be trimmed. The selected entities are trimmed to the boundary defined by the two bounding entities or face.

In Offset Trim, the user selects two entities or a face and then selects the entities to be trimmed. The selected entities are trimmed to the offset region defined by the two bounding entities or face.
