when adding vectors in two dimensions, which statements are correct?
the vectors can be added, then subtracted as if they were in one dimension, then these results averaged for the two - dimensional sum.
the resultant vector always points from the tip of the first vector to the tail of the last vector.
a protractor and ruler can be used to draw the vectors with the correct angles and magnitudes, so that the resultant vector can then be measured.
the resultant always points from the tail of the first vector to the tip of the final vector.

Explanation:

Step1: Analyze vector addition properties

Vectors can be added and subtracted in two - dimensional space as if they were in one - dimensional space in terms of component - wise operations.

Step2: Analyze resultant vector direction

The resultant vector does not always point from the tip of the first vector to the tail of the last vector. The correct way is from the tail of the first vector to the tip of the last vector.

Step3: Analyze protractor and ruler usage

A protractor and ruler can be used to draw vectors with correct angles and magnitudes so that the resultant vector can be measured.

Answer:

The vectors can be added, then subtracted as if they were in one dimension, then these results averaged for the two - dimensional sum. A protractor and ruler can be used to draw the vectors with the correct angles and magnitudes, so that the resultant vector can then be measured.
