Key Definitions | Description |
---|---|

Equilateral Triangle | A triangle with all three sides of equal length and all three angles equal to 60 degrees. |

Cevian | A line segment extending from a vertex of a triangle to the opposite side (or its extension). |

Angle of 60 Degrees | The measure of the angle formed between cevians AD and CE in the equilateral triangle. |

Side AC | The length of the side AC in the triangle, which needs to be proven as equal to the sum of the lengths of segments AE and CD. |

Segments AE and CD | The lengths of segments AE and CD which, when added together, are to be proven equal to the length of side AC. |
