Looking for fads, making a conjecture, and verifying the conjecture. You are watching: Two angles whose sides are opposite rays are called | |

Unidentified terms | Point, line, and also airplane. |

Segment | Consists of 2 endpoints and all points that lie on the line in between those endpoints. |

Ray | Consists of an initial suggest and all points on the line that lay on either one side of the endpoint or the various other. |

Collinear | Points, segments, or rays that lie on the same line. |

Angle | Two various rays that have actually the exact same initial suggest. |

Acute | An angle whose measure is between 0 and 90 degrees. |

Right | An angle whose meacertain is exactly 90 degrees. |

Obtuse | An angle whose meacertain is in between 90 and 180 degrees. |

Straight | An angle whose measure is precisely 180 levels. |

Reflex | An angle whose measure is in between 180 and 360 levels. |

Interior | A suggest that lies between points that lie on each side of an angle. |

Exterior | A point that does not lie in the interior of an angle, or on the angle. |

Adjacent | Two angles that share a widespread vertex and side, but have no prevalent internal points. |

Postulates | Rules in geomeattempt which have to be welcomed as true without proof; likewise dubbed axioms. |

Ruler Postulate | The points on a line can be matched one-to-one via the set of genuine numbers, which allows you to determine the coordinate of a suggest and also the distance in between points. |

Segment Addition Postulate | If B is between A and C, then AB+BC=AC. |

Protractor Postulate | The rays that create an angle have the right to be put in one-to-one correspondence through the real numbers between 0 and 180 levels inclusive, which permits angles to be measured. |

Angle Addition Postulate | Allows you to add the actions of adjacent angles. |

Congruent | Two segments or angles having actually the very same meacertain. |

Midpoint | The allude that divides a segment right into 2 congruent segments. |

Segment bisector | A segment, ray, line, or airplane that intersects a segment at its midsuggest. |

Angle bisector | A ray that divides an angle right into 2 congruent angles. |

Perpendicular | Two lines that intersect to develop a best angle. |

Distance formula | A formula used to calculate the distance in between 2 points in a coordinate airplane. |

Hypothesis | In a conditional statement, the part following the "if" delisted by "p". |

Conclusion | In a conditional statement, the component adhering to the "then" delisted by "q". |

Conditional statement | A logical statement that have the right to be created in "if-then" develop. |

Converse | A conditional statement developed by interaltering the hypothesis and also conclusion. |

Counterexample | One instance offered to show that a conditional statement is false. |

Biconditional statement | A true conditional statement whose converse is likewise true. |

Reflexive | Any geometric object is congruent to itself. |

Symmetric | If one geometric object is congruent to a second, then the second is congruent to the initially. |

Transitive | If one geometric object is congruent to a 2nd, and also the second is congruent to a third, then the initially object is congruent to the 3rd object. |

Vertical angles | Two angles whose sides develop two pairs of opposite rays. |

Linear pair | Two nearby angles whose nonprevalent sides are oppowebsite rays. |

Complementary | Two angles whose measures amount to 90 degrees. |

Supplementary | Two angles whose steps amount to 180 levels. |

Liclose to Pair Postulate | If 2 angles create a straight pair, then they are supplementary. |

Vertical Angles Theorem | If 2 angles are vertical angles, then they are congruent. |

Congruent Supplements Theorem | If two angles are supplementary to the very same angle or to congruent angles, then they are congruent. |

Congruent Complements Theorem | If 2 angles are complementary to the very same angle or to congruent angles, then they are congruent. See more: List Of Words That End In Art ', List Of Words Ending With 'Art' |

Deductive reasoning | To reason from well-known facts; supplied once proving a theorem. |
