Final answer:
Since the question about the next step in a construction is unclear in terms of context, a general answer for a vector addition scenario is that after drawing two vectors and connecting points, one would typically measure the resultant vector if all vectors have been added, or continue adding more vectors if applicable.
Step-by-step explanation:
The construction steps provided seem to relate to a geometric construction or vector addition problem in mathematics. However, the question lacks clear context regarding the initial construction to provide the accurate next step. In typical vector addition sequences, as seen in the reference steps provided, the next step after drawing vectors and connecting points would be to measure the resultant vector if all vectors have been added graphically.
For geometric constructions involving congruent shapes or translation of points, the steps might differ slightly. Considering vector addition, if there are only two vectors as mentioned in Figure 3.13, the process would be complete after placing arrows tip to tail. If not, one would continue adding vectors in the stated manner.
If the context is indeed vector addition, the references indicate that after drawing the second vector and connecting the designated points, one should review the construction and the given vectors to ensure they correctly represent the vector addition sequence, such as tip to tail from the starting point to the last point marked. Without further information, it would be advisable to confirm the initial setup and what the construction aims to demonstrate or solve.
