transformations Transformations are different ways to move a figure. Three kinds of TRANSFORMATIONS are: reflections, translaitons, and rotations.
translation When you slide a figure, it is a TRANSLATION.
reflection When you flip a figure over a line, it is a REFLECTION.
rotation When you turn a figure around a point or vertex, it is a ROTATION.
congruent figure CONGRUENT FIGURES have the same size and the same shape.
point symmetry A figure has POINT SYMMETRY if it can be turned about a central point still look the same in at least two different positons.
line symmetry Another kind of symmetry is LINE SYMMETRY. A figure has line symmetry when it can be folded about a line so that it's two parts are identical. When you unfold the figure, one side is a reflection of the other. A figure can have more than one LS.
