- A regular octagonal pyramid of base side...

Q. |
## A regular octagonal pyramid of base side equal to 6 cm is resting on its octagon face on ground and section plane is parallel to axis and not parallel to any of the edges of base is held at a distance of 4 cm away from axis the section will be |

A. | triangle |

B. | trapezium |

C. | rectangle |

D. | octagon |

Answer» A. triangle | |

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 a triangle. |
