Question

we constructed $overline{cd}$ as a copy of $overline{ab}$, as shown in the image. what was the last step that we did to complete this construction? (1 point) using a compass, we measured the length from point a to point d using a compass, we measured the length from point c to point d using a straightedge, we constructed a line from point c to point d using a straightedge, we constructed a line from point a to point b

Explanation:

To construct a copy of line - segment $\overline{AB}$ as $\overline{CD}$, after setting the compass width to the length of $\overline{AB}$ (using the compass to measure from $A$ to $B$), the last step is to use a straightedge to draw a line from point $C$ to the point marked as $D$ (after marking the distance with the compass from $C$).

Answer:

C. Using a straightedge, we constructed a line from point $C$ to point $D$
