What is an example of reflection in math?

For example, suppose the point (6, 7) is reflected over y = x. The coordinates of the reflected point are (7, 6). Likewise, reflections across y = -x entail reversing the order of the coordinates, but also switching their signs. For example, (8, -2) turns into (2, -8) when reflected over the line y = -x.

How do you explain a reflection in math?

In Geometry, a reflection is known as a flip. 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 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 a reflection Maths ks3?

If you look in a mirror, you see your own image. You (the object) and your image appear to be the same distance from the mirror. An object and its image are always the same perpendicular distance from the mirror line.

What does reflection mean in maths KS2?

This KS2 Maths video explains how shapes can be transformed through translation, reflection or rotation. Reflection is a type of transformation. To reflect an object, you need a mirror line. When a shape is reflected, its size does not change – the image just appears ‘flipped’.

What is the rule for the reflection?

Every point on one shape will have its corresponding point at the same distance from the y -axis on the opposite side of the y -axis. A reflection over y -axis generates a figure of the same shape and size as the original, flipped over the y -axis.

What is reflection BBC Bitesize?

When light from an object is reflected by a surface, it changes direction. It bounces off the surface at the same angle as it hits it. Smooth, shiny surfaces such as mirrors and polished metals reflect light well. Dull and dark surfaces such as dark fabrics do not reflect light well.
