What are the two rules of reflection?

The laws of reflection are as follows:The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.More items…

What information is needed to describe a reflection?

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. When describing a rotation, the centre and angle of rotation are given.

Why is it called a reflection?

Reflection comes from the idea of “self-examination, self-modification, and self-replication”, reflecting on one’s self for the purpose of change. In programming you use reflection to examine the structure of the program itself in the context of using it instead of just examining it.

How do you describe reflection?

A reflection is a type of transformation. It ‘maps’ one shape onto another. When a shape is reflected a mirror image is created. If the shape and size remain unchanged, the two images are congruent.

What are properties of reflection?

Basic Properties of Reflections: (Reflection 1) A reflection maps a line to a line, a ray to a ray, a segment to a segment, and an angle to an angle. (Reflection 2) A reflection preserves lengths of segments. (Reflection 3) A reflection preserves measures of angles.
