Plane figures and solids can be changed (or transformed) by translation, reflection and dilation. The symmetry of shapes is related to translation, reflection and rotation. Triangle ABC and its reflection A'B'C' have the same size and shape, that is they are congruent. A translation is defined by specifying the distance and the direction of a movement. For example, triangle ABC is translated by 2 units to the right. Triangle ABC and its image A'B'C' have the same size and shape.
Reflections: How to reflect a point. Reflect point across x axis, y axis and other lines. A reflection is a kind of transformation. It is basically a 'flip' of a shape over the line of reflection. Very often reflecions are performed using coordinate notation as they all are on this page.
