2 TYPES OF TRANSFORMATIONS Reflection – The flip of a figure over a line to produce a mirror image.Rotation – A geometric turn of a figure around a fixed point.Translation – The slide of a figure from one position to another.Dilation – A transformation that alters the size of a figure, but not its shape.
3 Preimage to ImageB’A’C’BIts matching point on the corresponding figure is called its image.D’ACDEach point on the original figure is called the Preimage
4 ReflectionsREFLECTION – The flip of a figure over a line to produce a mirror image.
5 Coordinate Reflection The triangle is reflected about the x-axis. Each point is equal distance from the x-axis.
6 Coordinate Translation Each point is translated 3 points to the right and 5 points up.
7 RotationROTATION – A geometric turn of a figure around a fixed point.D’A’900PDA
8 TranslationSlideTRANSLATION– The slide of a figure from one position to another.
9 DilationDilation is altering the size of the figure by k = n . The dilation of this figure is k = 3. The image is 3 times bigger than the preimage.DILATION – A transformation that alters the size of a figure, but not its shape.
10 Coordinate DilationEach point is multiplied by k to find the dilation.
