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

Point | The geometric figure formed at the intersection of two distinct lines |

Line | The geometric figure formed by two points. A line is the straight path connecting two points and extending beyond the points in both directions. |

Angle | Two rays sharing a common endpoint. Angles are typically measured in degrees or radians. |

Ray | A part of a line starting at a particular point and extending infinitely in one direction. |

Convex | A geometric figure with no indentations. Formally, a geometric figure is convex if every line segment connecting interior points is entirely contained within the figure's interior. |

Concave | A shape or solid which has an indentation or "cave". Formally, a geometric figure is concave if there is at least one line segment connecting interior points which passes outside of the figure. |

Fraction | A ratio of numbers or variables. Fractions may not have denominator 0. |

Oblique | Tilted at an angle; neither vertical nor horizontal. |

Plane | A flat surface extending in all directions. Any three noncollinear points lie on one and only one plane. So do any two distinct intersecting lines. A plane is a two-dimensional figure |

Quadratic | An equation, graph, or data that can be modeled by a degree 2 polynomial |
