Transformations Test Review

A transformation is an operation that moves or changes a shape in some way to produce a new shape.

The four main types of transformations are translation, rotation, reflection, and dilation.

Translation is a transformation that slides a figure in a straight line from one position to another without changing its size, shape, or orientation.

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

A reduction occurs when the scale factor is less than 1.

Two figures are similar if they have the same shape but may have different sizes.

A reflection transformation produces a mirror image of a figure across a line of reflection.

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Congruent figures are identical in shape and size, while similar figures have the same shape but may differ in size.

The new coordinates will be (x + a, y + b), where 'a' is the horizontal shift and 'b' is the vertical shift.
