Question 12a - 12c

Cedar City has two city parks and is in the process of designing a third park. The planning committee would like all three parks to be equidistant from one another to better serve the community. A sketch of the city with the centers of the existing parks labeled as P1 and P2 is shown.

Question 12a

What 2 dimensional shape can be used to model this situation. Be as specific as possible (Hint: the answer is NOT circle.)

Question 12b

Identify two possible locations for the third park, and label them as A and B on the map.

Question 12c

The city decided to build the park at location B. Use the SEGMENT TOOL to draw the 2 dimensional shape that proves that the 3 parks will be equidistant from one another. Then use the MOVE TOOL (the mouse icon) to turn the 2 dimensional shape red.
