Key Terms1. Transformation – an operation that maps an
original geometric figure onto a new figure called the image.

Translation• Called a slide• Image is the same shape and the same size as
the original figure• You slide a figure from one position to
another without turning it.• When translating a figure, every point of the
original figure is moved the same distance and in the same direction.

Triangle LMN has vertices L(-1, -2), M(6,-3) and N(2,-5). Find the vertices of Triangle L’M’Nafter a translation 6 units to the left and 4 units up.

Relection
• Called a flip• Figures are mirror images of eachother• Image is the same shape and same size as the
original figure• Orientation is different from the original
figure• When you flip a figure over a line.• This line is called the line of symmetry.

• Reflection over the x = x stays the same and find the opposite of the y
• Reflection over the y – y stays the same and find the opposite of the x.
