Question
A line that is perpendicular to the plane of the horizon.
- vertical
- horizontal
- diagonal oblique
- oblique diagonal
Hint:
1. Plane of the horizon refers to the straight horizontal surface/ line that appears at the end of the visible earth surface and beginning of the sky.
2. A line that intersects any other given line at a 90° angle is said to be perpendicular to the given line.
3. A straight line that is parallel to the Y-axis and that goes from to top to bottom and vice versa is called a vertical line.
4. A straight line that is parallel to the X-axis and that goes from left to right and vice versa (sideways) is called a horizontal line.
The correct answer is: vertical
GIVEN-
A line which is perpendicular to the plane of horizon.
TO FIND-
Nature of the perpendicular line.
SOLUTION-
We know that the plane of horizon is a horizontal line and
We are given that a line is perpendicular to the plane of horizon.
Hence, this line intersects the plane of horizon at a 90° angle.
And we know that any line that is at a 90° angle with a horizontal line is a vertical line.
Hence, the given line is a vertical line.
FINAL ANSWER-
Option 'a' i.e. 'vertical' is the correct answer to the given question.

A straight path with points in a plane that continues without end in both directions.
A path is not a point but a collection of points in a straight path. Hence, option d is eliminated.
Also, a line segment and a ray are both parts of a line where a line segment has fixed or definite ends on both sides whereas a ray has one end fixed and the other end extends infinitely.
Hence, options b & c are also eliminated.
