## What is a line of reflection?

Ll. line of reflection. • a line midway between something, called a pre-image, and its mirror reflection.

## How do you reflect a line in geometry?

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-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

## What is a reflection point in geometry?

In Geometry, a reflection is known as a flip. A reflection is a mirror image of the shape. A figure is said to be a reflection of the other figure, then every point in a figure is at equidistant from each corresponding point in another figure. …

## What is another name for a line of reflection?

Line Symmetry

Another name for reflection symmetry. One half is the reflection of the other half. The “Line of Symmetry” (shown here in white) is the imaginary line where you could fold the image and have both halves match exactly.

## How do you teach reflections in geometry?

To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. Corresponding parts of the figures are the same distance from the line of reflection. Ordered pair rules reflect over the x-axis: (x, -y), y-axis: (-x, y), line y=x: (y, x).

## What is the another name of line of symmetry?

The line of symmetry is also called the mirror line or axis of symmetry. A circle has infinite lines of symmetry.

## How do you describe reflection?

A reflection is like placing a mirror on the page. When describing a reflection, you need to state the line which the shape has been reflected in. The distance of each point of a shape from the line of reflection will be the same as the distance of the reflected point from the line.

## How do you find reflections?

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-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
