What is reflection and rotation?
A reflection is the flipping of a point or figure over a line of reflection (the mirror line). A rotation is the turning of a figure or object around a fixed point.
What is matrix reflection?
A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a line of symmetry using a reflection matrix.
Is reflection the same as rotation?
Rotation means the shape turns as it moves around a fixed point. Shapes can be rotated clockwise or anticlockwise by a certain number of degrees (90 degrees would be a quarter turn, for example). Reflection means the shape has a mirror image on the other side of the mirror line.
