Term | Definition |
---|---|

Altitude of a Triangle | The perpendicular distance between a vertex of a triangle and the side opposite that vertex. Sometimes called the height of a triangle. Also, sometimes the line segment itself is referred to as this. |

Base (of a Polygon) | It can be any side for two-dimensional figures. Typically, however, it is the bottom side, on which the polygon "sits". |

Cubed Root | One of three identical factors of a number that is the product of those factors. |

Diameter | The distance across a circle through its center. The line segment that includes the center and whose endpoints lie on the circle. |

Hypotenuse | It is the side of a right triangle that is directly across from the right angle. This is also the longest side of any right triangle. |

Leg of a Triangle | Either of the two shorter sides of a right triangle. These two sides together form the right angle in the right triangle. |

Perfect Cubes | In arithmetic and algebra, the cube of a number n is its third power. It is the result of the number multiplying by itself three times. |

Pythagorean Theorem | A theorem that states that in a right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs. a^2 + b^2 = c^2 |

Pythagorean Triples | A set of positive integers, a, b, and c that fit the rule a^2 + b^2 = c^2. |

Radius | The distance from the center of a circle to any point on the circle. Also, the line segment that has the center of the circle as one endpoint and a point on the circle as the other endpoint. |

Right Triangle | A triangle with exactly one right angle. |

Volume | The amount of space occupied by an object. |

Domain | It is the set of all x-coordinates of the ordered pairs of a relation or the "input" of the relation. |

Function | A rule of two sets of numbers in which an input value from the first set has only one unique output value in the second set. In other words, a relation where each input has a unique output. |

Range | The set of all output values or the y-values of a relation. |
