Geometry symbols play a crucial role in expressing mathematical concepts and solutions. From familiar Math's symbols like "+", "-", "*", and "/", these evolve into specialized geometry symbols that visually represent geometric elements. These symbols, such as points (●), lines (―), and angles (∠), form the language of geometry, aiding in the precise communication of spatial relationships. The application of geometric symbols extends to different shapes like triangles (△) and circles (o), facilitating the representation and solution of geometric problems within the broader realm of Math's solutions.

Meaning / Definition |

∠ |
Angle |
Represents an angle formed by two rays sharing a common endpoint. |

m∠ |
Measured Angle |
Denotes the measure of an angle in degrees or radians. |

∢ |
Spherical Angle |
Represents an angle on the surface of a sphere. |

" |
Double Prime |
Indicates seconds in angular measurement (1 minute = 60 seconds). |

─→ |
Line |
Represents a straight path that extends indefinitely in both directions. |

AB or AB |
Line Segment |
Denotes a part of a line with two endpoints. |

→AB or AB→ |
Ray |
Represents a part of a line that starts at one endpoint and extends indefinitely in one direction. |

↺ |
Arc |
Represents a curved part of a circle. |

⊥ |
Perpendicular |
Denotes two lines that intersect at a right angle. |

∥ |
Parallel |
Indicates lines that will never intersect. |

≅ |
Congruent To |
