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

Transversal | A line that intersects two coplanar lines at two distinct points |

Segment | The part of a line consisting of two endpoints |

Coplanar | Points and lines that lie on the same plane |

Adjacent | Two coplanar angles with a common side, a common vertex, and no common points |

Midpoint | A point ona segment that divides a segment into two congruent segments |

Concave | A polygon with at least one diagonal that falls outside the polygon |

Complementary | Two angles whose measures have a sum of 90 degrees |

Obtuse | An angle whose measure is greater than 90 degrees |

Corresponding | Two angles that are in the same position on a transversal |

Straight | An angle whose measure is equal to 180 degrees |

Skew | Two or more noncoplanar lines |

Hypotenuse | The longest side of a right triangle |

Orthocenter | The point of concurrency of the altitudes of a triangle |

Parallel | Two or more coplanar lines that do not intersect |

Centroid | The point of concurrency of the medians of a triangle |

Altitude | The perpendicular segment from a vertex to the line containing the opposite side |

Supplementaty | Two angles whose measure have a sum of 180 degrees |

Median | A segment in a triangle whose endpoints are a vertex and the midpoint of the opposite side |

Acute | An angle whose measure is less than 90 degrees |

Concurrent | When three or more lines intersect at one point |

Circumcenter | The point of concurrency of the perpendicular bisectors of a triangle |

Vertical | Two angles whose sides form two pairs of opposite rays |

Convex | A polygon with no diagonals that lie outside the polygon |

Polygon | A closed plane figure with at least three sides that are segments, the sides only intersect at their endpoints |

Inverse | Negates both of the hypothesis and conclusion of a conditional |

Contrapositive | Switches the hypothesis and the conclusion and negates both of them |

Converse | Switches the hypothesis and conclusion in an "if-then" statement |

Incentor | The point of concurrency of the angle bisectors of a triangle |

Conditional | Another name for an "if-then" statement |

Midsegment | A segment in a triangle connecting the midpoints of two sides |

Regular | A polygon with all sides and angles the same |

Right | An angle whose measure is equal to 90 degrees |

CPCTC | Used to prove angles or sides of triangles are congruent |
