Q. |
## A regular pentagonal pyramid of base side equal to 5 cm is resting on H.P on its pentagon face and section plane is parallel to axis and parallel to edge of base and plane is 2 cm away from axis. The section will be |

A. | triangle |

B. | trapezium |

C. | rectangle |

D. | pentagon |

Answer» B. trapezium | |

Explanation: if a pyramid is cut by a plane parallel to axis and also parallel to any edge of base then the section formed will be trapezium if the section plane not parallel to edge of base then the section will be triangle. |
