Chapter 10.1, Problem 5P

Ed the robot is standing at point A and will walk to point D along the route shown on the map in Figure 10.32. 0n the map. each segment between two dots represents 10 of Ed‘s paces.

A. Trace or redraw the map in Figure 10.329. At the points where Ed will turn, indicate his angle of turning. Use a protector to measure these angles, an mark themon the map

 

Figure 10.32 ED’s route

B. Ed is a robot, so you must tell Ed exactly how to walk to point D. At points where Ed must turn, tell him how many degrees to turn, and which way.

C. Determine Ed’s total amount of turning along his route by adding the angles you measured in part (a).

D. Now determine Ed's total amount of turning along his route without measuring the individual angles and adding them. Hint: Consider the directions that Ed faces as he travels along his route
