a three-dimensional shape | solid; |

(mathematics) an unbounded two-dimensional shape | plane; sheet; |

a plane in which all points can be described in Cartesian coordinates | cartesian plane; |

a geometric representation of the complex numbers established by the real axis and the orthogonal imaginary axis; it can be thought of as a modified Cartesian plane, with the real part of a complex number represented by a displacement along the x-axis, and the imaginary part by a displacement along the y-axis | complex plane; |

the plane of a facet of an object (as of a cube) | facet plane; |

the median plane of the body (or some part of the body) | midline; midplane; |

(astronomy) the plane on which a body is orbiting | orbital plane; |

the plane that is in the foreground of a drawing or painting; coextensive with but different from the objective surface of the work | picture plane; |

the plane that contains all the lines tangent to a specific point on a surface | tangent plane; |

a shape created by natural forces; not man-made | natural shape; |

any of the various shape that leaves of plants can assume | leaf form; leaf shape; |

a figure whose sides are all equal | equilateral; |

a shape that spreads outward | flair; flare; |

a combination of points and lines and planes that form a visible palpable shape | figure; |

a figure formed by a set of straight lines or light rays meeting at a point | pencil; |

a two-dimensional shape | plane figure; two-dimensional figure; |

a three-dimensional shape | solid figure; three-dimensional figure; |

a figure that is a part of another figure | subfigure; |

a length (straight or curved) without breadth or thickness; the trace of a moving point | line; |

anything with a round shape resembling a teardrop | bulb; |
