Wei constructed CD as a copy of AB, as shown in the image. What was the last step that Wei did to complete his construction?

Question

a. Using a compass. he measured the length from point C to point D
b. Using a compass. he measured the length from point A to point B
c. Using a straightedge. he constructed a line from point A to point B
d. Using a straightedge. he constructed a line from point C to point D

Answer 1

To determine the last step that Wei did to complete his construction of CD as a copy of AB, we need to analyze the options:

a. This option indicates measuring the length from C to D using a compass, but you generally measure lengths before placing points.

b. This option suggests measuring the length from A to B using a compass. This is likely a step that would happen before placing point D.

c. This option describes constructing a line from A to B using a straightedge. This step would be part of the initial setup and not the final step.

d. This option describes constructing a line from C to D using a straightedge. This action would finalize the construction of the segment CD that is equal to segment AB.

Given this analysis, the last step that Wei did to complete his construction was:

d. Using a straightedge. he constructed a line from point C to point D.
