Question | Answer |
---|---|

coordinate plane | a plane formed by the intersection of a horizontal number line (x-axis) with a vertical number line (y-axis) |

x-axis | the horizontal axis (side to side) |

y-axis | the vertical axis (up and down) |

ordered pair | a point in the coordinate plane named (x,y) |

origin | the point where the x-axis and the y-axis meet; (0,0) |

translation | a movement (slide) of a figure along a straight line |

reflection | a change in position of a figure that flips the figure across a line |

dilation | a change in the size of a figure which either reduces or enlarges the picture |

rotation | a change in position of a figure around a fixed point |

similar figures | figures that are the same shape, but are a different size;all of the corresponding parts of the figures have the same ratio |

congruent figures | figures that are the exact same shape and size |

parallel lines | two or more lines in the same plane that never intersect |

transversal | a line that intersects at least two other lines |

corresponding angles | a pair of angles at matching intersections of the parallel lines and the transversal |

alternate interior angles | a pair of angles in between the parallel lines that are on the opposite sides of the transversal |

alternate exterior angles | a pair of angles outside the parallel lines that are on the opposite sides of the transversal |

same side interior angles | a pair of angles in between the parallel lines that are on the same side of the transversal |

sequence of transformations | a set of transformations (translations, reflections, dilations, and rotations) in the coordinate plane that must occur in a specific order to obtain a new figure |
