How is copying a line segment similar to copying an angle?

answer: there are some facts which are similar in copying line segments and angles : -

we use a straightedge and compass to draw a copy of line segment or copy of an angle on paper. to create a copy of an angle , two line segments are created by copying them from the original angle.

that is how copying a line segment is similar to copying an angle.

An angle is created from two line segments. use a straightedge to draw a similar figure on your paper. then, use the straightedge and compass to copy the figure exactly. to copy this figure, you will need to copy both the line segments and the angle.
