Chapter 13.8, Problem 3WE

To determine

To find: the missing coordinate of the given figures without introducing any new letters.

Answer to Problem 3WE

The missing coordinates are $\left(\text{-f,2f}\right)\text{and}\left(\text{f,2f}\right)$

Explanation of Solution

Given information : The given figure of square is shown below

  

It is known that the sides of square are equal.

It is given that the coordinates in x-axis are $\left(\text{-f,0}\right)\text{and}\left(\text{f,0}\right)$

Therefore, the sides of the square will be $\text{f-}\left(\text{-f}\right)\text{=2f}$

Hence, in the positive side of y-axis the missing coordinates are $\left(\text{-f,2f}\right)\text{and}\left(\text{f,2f}\right)$
