To find: The congruency of image of the arctic
Answer to Problem 17WE
The image of equator and Arctic circle will be congruent.
Explanation of Solution
Given information:
It is given that a piece of paper is wrapped around a globe of earth to form a cylinder as shown.
Calculation.
If the equator is the line of latitude that is the longest and lie along the circumference of the globe and divides the globe into the northern and southern hemisphere, the images of all points on the equator will lies on the paper as circle.
Similarly, Arctic Circle is one of the five major circles of latitude. The images of all points of the Arctic Circle will lies on the paper in a form of circle. And because of the shape of the paper, a cylindrical shape, the circles will be congruent.
Therefore, the image of equator and Arctic Circle will be congruent.
