This time, shift the focus from the points towards the resulting image of the circle after being reflected over $y = x$. {/eq}-axis. If this value right over here, its absolute value was greater than one, then it would stretch it vertically, or would make it thinner in of point A across which axis? Now we're going to go WebWe can use matrices to translate our figure, if we want to translate the figure x+3 and y+2 we simply add 3 to each x-coordinate and 2 to each y-coordinate. Get Solution. A reflection over a line k (notation rk) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line. The y-coordinate will be the midpoint, which is the average of the y-coordinates of our point and its reflection. Use the reflection tool (9th tool over, under the reflection diagram) 5) Select the Triangle ABC, then y-axis. Construct the line of reflection as a guide and double-check whether the reflection was performed correctly. One side should be perpendicular to the other side. will be the perpendicular bisector of the segment joining point P to point P. Just like looking at a mirror image of yourself, but flipped.a reflection point is the mirror point on the opposite side of the axis. Well we want that when X is equal to two to be equal to negative one.
