Consider the series of transformations shown in the figures above. The first is R (6,4),90°, or a clockwise rotation of 90° about the point (4, 6). The second transformation is r y =0, or a reflection across the x-axis. Together they are a composition of transformations , which is two or more transformations performed in sequence.
Reflections A third type of transformation is the reflection . The figure below shows triangle A B C reflected across the line y = x + 2 . This reflection can be described in coordinate notation as ( x , y ) → ( y − 2 , x + 2 ) . (Again, you can check this by plugging in the coordinates of each vertex.)

Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them. 8.G.A.3.
Reflection. In geometry, a reflection is a type of transformation in which a shape or geometric figure is mirrored across a line or plane. It is also referred to as a flip. A reflection is a rigid transformation, which means that the size and shape of the figure does not change; the figures are congruent before and after the transformation.

•5: Congruence, Proof, and Constructions In Unit , you will define transformations in terms of rigid motions. Geometry and algebra merge as you apply rotations, reflections, and translations to points and figures while using function notation. You will also explore triangle congruency, and construct lines, segments, angles, and polygons.

Congruence transformations are also called isometries. Two figures that can be transformed into each other by a congruence transformation are said to be congruent. Congruence transformations of the plane include translation, rotation, reflection, glides, and the identity map.
