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

An angle whose measure is between 0 and 90 | Acute Angle |

Two coplanar angles that have a common side and a common vertex but no common interior points | Adjacent Angles |

Formed by two rays with the same endpoint. The rays are the sides of endpoint is the vertex of the angle | Angle |

A ray that divides an angle in two congruent angles | Angle Bisector |

Points lie on the same line | Collinear |

A geometric tool used to draw circles | Compass |

Two Angles that measure the same if their measure is 90 | Complementary Angle |

Two angles that have the same measure | Congruent |

Two segments that have the same length | Congruent |

Conclusion reached by using a inductive reasoning | Conjecture |

Using only a straight edge and compass to make a geometric figures | Construction |

The point on a number line is its distance and direction from the orgin | Coordinate |

Points and lines in the same place | Coplanar |

Deductive Reasoning | Process of reasoning logically from given facts to a conclusion |

Type of reasoning that reaches conclusions based on a pattern of specific examples or past events | Inductive Reasoning |

A series of points that extend without end. | Line |

Angles are measured in degrees | Measurement of an angle |

An angle whose angle measure is between 90 and 180 degree | Obtuse Angle |

Collinear rays with the same endpoint they form a line | Opposite Rays |

These lie on the same plane and don't intersect | Parallel Lines |

Planes that do not intersect | Parallel Planes |

A segment, ray. line, or plan that is perpendicular to the segment at its midpoint | Perpendicular Bi-sector |

If two lines intersect and form angles | Perpendicular Lines |

A flat surface that extends in all directions without end. | Plane |

A location, it has no size | Point |

An accepted statement of fact. | Postulate |

A convincing argument that uses deductive reasoning | Proof |

The four sections of a coordinate plane | Quadrant |

The halfway point of two congruant segment | Midpoint |

Part of a line consisting of one endpoint and all the points of the line on one side of the endpoint | Ray |

Part of a line consisting of the two points called endpoints and all points between them. | Segment |

An angle whose measure is 90 degrees | Right Angle |
