Chapter 4.8, Problem 13PPS

To determine

The names of the missing coordinates in given figure.

Answer to Problem 13PPS

  $Y\left(a,0\right)\text{ and C}\left(a,a\right)$

Explanation of Solution

Given:

The given figure is:

  

Calculation:

As point Y is on the x-axis, its y-coordinate will be 0.

As the line segment CY is perpendicular to x-axis, the x-coordinate of point C is equal to the x-coordinate of point Y.

As, ZY = CY, the y-coordinate of C will be a such that CY = a.

Hence,

  $Y\left(a,0\right)\text{ and C}\left(a,a\right).$
