A reflection is a kind of transformation. Conceptually, a reflection is basically a 'flip' of a shape over the line of reflection. Reflections are opposite isometries, something we will look below.
A reflection is a flip over a line. You can try reflecting some shapes about different mirror lines here: "How Do I Do It Myself?" Just approach it step-by-step. For each corner of the shape: 1. Measure from the point to the mirror line (must hit the mirror line at a right angle) 2. Measure the same distance again on the other side and place a dot.
Flips (Reflections): A flip is also called a reflection. You can see the result of a flip or a reflection in a shape that has line symmetry, so line symmetry is related to the movement that is a reflection or a flip. The word flip comes from the idea of making the movement using a shape drawn on a piece of paper.

In geometry, a reflection is a rigid transformation in which an object is mirrored across a line or plane. When an object is reflected across a line (or plane) of reflection, the size and shape of the object does not change, only its configuration; the objects are therefore congruent before and after the transformation. The figure below shows sever...
There are a number of different types of reflections in the coordinate plane. The most common cases use the x-axis, y-axis, and the line y = x as the line of reflection.
A line of reflection is also a line of symmetryif a geometric shape or figure can be reflected across the line back onto itself. Reflecting the right side of the butterfly across line l maps it to the butterfly's left side. The same result occurs if the left side of the butterfly is reflected across line l, so line l is also a line of symmetry. You...
A glide reflection is a combination (also referred to as a composition) of a translationfollowed by a reflection. The preimage of a concave hexagon is translated to the right then reflected across the line of reflection to produce the final image shown above.
Simple reflections are a matter of looking at a line and a point, line, or polygon on one side of it. You want to figure out the distance between the two and take that point, line, or polygon and put it the distance away from the line, but on the opposite side.
- Great question! Let A be the point to be reflected, let k be the line about which the point is reflected, let B represent the desired point (image)...
- The reflection line is the line that you are reflecting over. Y=mx+b is just the basic slope-intercept equation. If you don't understand slope -int...
- count the spaces between the line you are reflecting over
- wow that is bonkers
- There is a part that says "I want to see Sal doing a similar question" which helped me since I was having trouble.
- Yep, just plug the coordinates for each point into the point-slope equation that is given to get the reflected points. Eg. In the last example in t...
- No questions are stupid! y=-1-x and y=x are both lines. When you reflect a point, it is an equal distance away from the line as your original point...
- When 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-coordin...
Like other functions, f (x) = a g (bx), if a is negative (outside) it reflects across x axis and if b is negative it reflects across the y axis. So for square root functions, it would look like y = a √ (bx). Outside reflect across x such as y = -√x, and inside reflect across y such as y = √-x.

A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection. A figure is said to reflect the other figure, and then every point in a figure is equidistant from each corresponding point in another figure.
