Q. |
## A plane is perpendicular to vertical plane and vertical trace of a plane is making 55 degrees with the xy plane. Which of the following is false? |

A. | the plane is inclined 55 degrees with the horizontal plane |

B. | front view gives a line |

C. | top view gives true shape of plane |

D. | horizontal trace is perpendicular to xy plane |

Answer» C. top view gives true shape of plane | |

Explanation: when a plane is perpendicular to one of the reference planes and inclined to the other, its inclination is shown by an angle which its projection on the plane to which it is perpendicular, makes with xy. and converse for traces. |
