Exercise 10 Page 585

Think about segments that have the same x-coordinate or the same y-coordinate.

Yes
Explanation: See solution.

Practice makes perfect

Yes it's possible, but only for segments that are either horizontal or vertical.

Vertical segments: The length of a vertical segment is the absolute value of the difference of the endpoints' y-coordinates.
Horizontal segments: The length of a horizontal segment is the absolute value of the difference of the endpoints' x-coordinates.

Let's illustrate this for two segments, one vertical and one horizontal.
