a. Flgure 10.87 shows 3 pairs of parallel line segments of the same length. In each case, describe how to get from point A to point B and from point C to point D by traveling along grid lines. Compare the instructions.
b. Flgure 10.88 shows 3 pairs of perpendicular line segments of the same length. In each case, describe how to get from pointA to point B and from point C to point D by traveling along grid lines. Compare the instructions and describe how they are related.
c. Copy the 3 line segments in Figure 10.89 onto graph paper (feel free to spread them out across the page) and use what you discovered in parts (a) and (b) to help you draw 3 squares that have those line segments as one side. Say briefly how to use the grid lines to draw the
