Reflection Transformation Rules Math

To determine the image point when performing reflections rotations translations and dilations use the following rules.

Reflection transformation rules math. Transformations reflection rules for performing a reflection across an axis 1. A reflection is sometimes called a flip or fold because the figure is flipped or folded over the line of reflection to create a new figure that is exactly the same size and shape. M a b 3 m a b 3 m b c 4 m b c 4 m c a 5 m c a 5. The graph of the original function looks like this.

The first flipping upside down is found by taking the negative of the original function. Coordinate rules for reflection if a b is reflected on the x axis its image is the point a b if a b is reflected on the y axis its image is the point a b if a b is reflected on the line y x its image is the point b a if a b is reflected on the line y x its image is the point b a geometry reflection. When reflecting across the y axis the y coordinates remain the same and the x coordinates change to their opposites. A transformation that uses a line that acts as a mirror with an original figure preimage reflected in the line to create a new figure image is called a reflection.

Though a reflection does preserve distance and therefore can be classified as an isometry a reflection changes the orientation of the shape and is therefore classified as an opposite isometry. That is the rule for this transformation is f x. The length of each segment of the preimage is equal to its corresponding side in the image. To see how this works take a look at the graph of h x x2 2x 3.

In coordinate geometry problems there are special rules for certain types of transformations. By allen ma amber kuang. The notation for this reflection would be. Since both begin align x end align coordinates only are multiplied by 1 the transformation is a reflection is in begin align y end align axis.

For example if we are going to make reflection transformation of the point 2 3 about x axis after transformation the point would be 2 3. When reflecting across the y axis the x coordinates remain the same and the y coordinates change to their opposites.
