Geometry - Transformations

What can we say is the general rule for a Rotation of (x, y)?

|O R I G I N A L |R O T A T I O N O F |N E W I M A G E |

|(x , y) |90 degrees | |

|(x , y) |180 degrees | |

|(x, y) |270 degrees | |

|(x , y) |360 degrees | |

In your own words, what is the rule for a reflection over the y-axis?

3. In your own words, what is the rule for a reflection over the x-axis?

In your own words, what is the rule for a reflection over the line y = x?

In your own words, what is the rule for a reflection over the line y = -x?

In your own words, what happens when you Translate something?

7. In your own words, what happens when you Dilate something?

8. The coordinates of the vertices of Triangle ABC are A(-1,3), B(2,6), and C(4,2). State the coordinates of the vertices of Triangle A”B”C” that result from the transformation [pic]

9. In the diagram below, [pic] and [pic] are graphed.

[pic]
