Question

d) how is copying a line segment similar to copying an angle?

Explanation:

Both involve using a compass. For copying a line - segment, the compass measures the length of the original segment and then marks the same length on a new line. For copying an angle, the compass is used to measure the arc - lengths on the original angle's rays and then replicate those arc - lengths to form an equal angle.

Answer:

Both use a compass in the construction process.
