In rectangle ABCD, if the coordinates of A are (0, 0) and the coordinates of C are (r, s), find the coordinates of B.With A and D being on the bottom line and B and C on the top with B over A.
A(0,0),B(0,s),C(r,s),D(r,0).
To find the coordinates of point B in the rectangle ABCD, we need to determine the x and y coordinates of B given the information of points A and C.
Since A is at (0, 0), it means the x-coordinate of A is 0 and the y-coordinate of A is also 0.
If C is at coordinates (r, s), it means the x-coordinate of C is r and the y-coordinate of C is s.
Since B is directly above A, the x-coordinate of B will be the same as the x-coordinate of A, which is 0. So, the x-coordinate of B is 0.
For the y-coordinate of B, we need to determine its value. Since B and C are on the top line and A and D are on the bottom line of the rectangle, we can conclude that the top line of the rectangle is parallel to the x-axis.
Since B is directly above A, the y-coordinate of B will be the same as the y-coordinate of the top line of the rectangle. The y-coordinate of the top line of the rectangle is the same as the y-coordinate of C, which is s.
Therefore, the coordinates of point B are (0, s).
