# Geometry Ch. test

### Ch. 3 test

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

parallel lines | coplanar, do not intersect |

perpendicular lines | intersect at 90 degree angles |

skew lines | not coplanar, not parallel, do not intersect |

parallel planes | planes that do not intersect |

transversal | a line that intersects two coplanar lines at two different points |

corresponding angles | lie on the same side of the transversal |

alternate interior angles | nonadjacent angles that lie on opposite sides of the transversal |

alternate exterior angles | lie on opposite sides of the transversal |

same-side interior angles | lie on the same side of the transversal |

corresponding angles postualte | if two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent |

alternate interior angles theorem | if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent |

alternate exterior angles theorem | if two parallel lines are cut by a transversal, then the two pairs of alternate exterior angles are congruent |

same-side interior angles theorem | if two parallel lines are cut by a transversal, then the two pairs of same side interior angles are supplementary |

converse of the corresponding angles postulate | if two coplanar lines are cut by a transversal so that a pair of corresponding angles are congruent, then the two lines are parallel |

converse of the alternate interior angles theorem | if two coplanar lines are cut by a transversal so that a pair of alternate interior angle are congruent, then the two lines are parallel |

converse of the alternate exterior angles theroem | if two coplanar lines are cut by a transversal so that a pair of alternate exterior angles are congruent, then the two lines are parallel |

converse of the same-side interior angles theorem | if two coplanar lines are cut by a trnansversal so that a pair of same-side interior angles are supplementary, then the two lines are parallel |

perpendiculare bisector | a line perpendicular to a segment at the segment's midpoint |

distance from a point to a line | the length of the perpendicular segment from the point to the line |

perpendicular transversal theorem | in a plane, if a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other line |

rise | the difference in the y-values of two points on a line |

run | the difference in the x-values of two points on a line |

slope | the ratio of rise to run. y2-y1/x2-x1 |

point slope form | y-y1=m(x-x1) |

slope-interept form | y=mx+b |

vertical line | x=a |

horizontal line | y=b |

(pairs of lines)parallel lines | same slope, different y-intercept |

intersecting lines | different slopes |

coinciding lines | same slope, same y-intercept |
