Linear Transformations--Directed Activity: Problem-Solving
Focus |
Using transformations to solve problems. |
Technologies |
Metric ruler and The Geometers Sketchpad and model 4_Camper.gsp |
Background |
As a camper is picking berries, he notices that his campfire has spread to the surrounding grass. He immediately runs to the river to fill his bucket with water for dousing the fire. Figure 4.12: The Camper, the Fire, and the River |
Tasks |
· In order to minimize the distance (and therefore the time) that the camper must run, what path should he follow in Figure 4.12? Use transformation geometry to find the path. · Justify your solution. |
