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

Acute Triangle | A triangle for which all interior angles measure less than 90 degrees |

Alternate Exterior Angles | Exterior angles on alternate sides of the transversal |

Alternate Interior Angles | Interior angles on alternate sides of the transversal |

Altitude of Triangle | Straight line through a vertex and perpendicular to a line containing the base of a triangle |

Angle Bisector Theorem (ABT) | Concerning the lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle & equates their lengths to the lengths of the other sides of the triangle |

ABT Converse | If a point is equidistant from the sides of an angle, then it is on the angle bisector |

Angle | Formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle |

Arc | A closed segment of a differential curve in the two-dimensional plane |

Area | Any particular extent of space or surface |

Bisector | A line that divides something into two equal parts |

Center of a Polygon | In a rotation, the point that does not move. The rest of the plane rotates around this fixed point |

Centroid of a Triangle | The point where the three medians of the triangle intersect |

Circumcenter of a triangle | The point where the three perpendicular bisectors of a triangle meet |

Circumference | A complete circular arc; also the distance around the outside of a circle |

Circumscribed | A geometric figure that is drawn around another geometric figure as to touch all its vertices |

Combination | A way of selecting several things out of a larger group, where order does not matter |

Common Parts | Informational language that describes similarities, differences, parts, and other attributes of two and three dimensional shapes, in different sizes and orentation |

Compass | An instrument for drawing circles and arcs and measuring distances between points, consisting of two arms linked by a moving joint |

Compliment Probability | In the probability theory, the compliment of any event A is the event [not A], i.e. the event that A does not occur |

Complementary Angles | Two angles that add up to 90 degrees |

Composition | The combining of distinct parts or elements to create a whole |

Compound Event | An event whose probability of occurrence depends upon the probability of occurrence of two or more independent events |

Compression | To reduce a shape in size while retaining proportions |

Conditional Probability | The probability that an event will occur, when another event is known to occur or to have occured |

Conditional Probability Formula | The conditional probability of A given B is denoted by P(AIB) and defined by the formula P(AIB)=P(AB) P(B), provided P(B)>o |

Congruence by AAS, ASA, SAS, SSS | Triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles |

Congruent | Identical in form |

Construction | The drawing of various shapes using only a straight edge and compass (no measurement of lengths or angles is allowed) |

Coordinates | On the coordinate plane, the pair of numbers giving the location of a point (ordered pair) |

Corresponding Angles | The angles in matching corners of a transversal |
