Q. |
## How many edges does a n vertex triangle free graph contains? |

A. | n2 |

B. | n2 + 2 |

C. | n2 / 4 |

D. | n3 |

Answer» C. n2 / 4 | |

Explanation: a n vertex triangle free graph contains a total of n2 / 4 number of edges. this is stated by mantel’s theorem which is a special case in turan’s theorem for r=2. |
