reflection
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated
rotation
A rotation is a circular movement of an object around a center of rotation
scale factor
A scale factor is a number which scales, or multiplies, some quantity
translation
In molecular biology and genetics, translation is the process in which cellular ribosomes create proteins
function
In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output
parabola
A parabola is a two-dimensional, mirror-symmetrical curve, which is approximately U-shaped when oriented as shown in the diagram below, but which can be in any orientation in its plane
symmetry
Symmetry in everyday language refers to a sense of harmonious and beautiful proportion and balance
Glide reflections
In 2-dimensional geometry, a glide reflection is a type of opposite isometry of the Euclidean plane: the composition of a reflection in a line and a translation along that line
non-rigid transformation
In mathematics, a rigid transformation of a vector space preserves distances between every pair of points
degree of rotation
Rotational symmetry, also known as radial symmetry in biology, is the property a shape has when it looks the same after some rotation by a partial turn
