Also, 99% of your problems with vertical slopes can be solved by saving the slope as a structure that … Web21. sep 2024 · We can extend the line and say that the line of reflection is x-axis when a polygon is reflected over the x-axis. Example 1: A polygon with the vertices A = ( − 10, 6) , B = ( − 8, 2), C = ( − 4, 4) and D = ( − 6, 7) is reflected over the x-axis. You are required to find out the midpoints and draw the line of reflection.

Web10. máj 2024 · For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P’, the coordinates of P’ are (-5,4).Notice that the y-coordinate for both points did not change, but the value of the x-coordinate changed from 5 to -5. You can think of reflections as a flip over a designated line of reflection.
WebWhen you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places … WebWell, one way to think about it is point A is exactly one, two, three, four units to the right of l. And so its reflection is going to be four units to the left of l. So if we go one, two, three, four, that would be the image of point A. We could maybe denote that as A prime.
