Question
_______ lines are lines that form 4 right (90 degree) angles.
- parallel
- intersecting
- perpendicular
- ray
Hint:
Perpendicular lines refer to those lines that cross (intersect) each other at a 90° angle. One of these lines is vertical while the other has to be horizontal.
The correct answer is: perpendicular
GIVEN-
The given lines form 4 right angles.
TO FIND-
Nature of the given lines.
SOLUTION-
We know that for 2 lines to intersect each other at right angles, one line has to be vertical while the other has to be horizontal.
And we know that perpendicular lines are a set of vertical and horizontal lines that cross each other at a 90° angle.
As we can see from the above diagram, perpendicular lines form 4 right angles.
FINAL ANSWER-
Option 'c' i.e. 'perpendicular' is the correct answer to the given question.

Identify the figure.
Intersecting lines are those that meet each other at a certain point on the plane whereas perpendicular lines are those which meet each other at a 90° angle.
Since in the given diagram the 2 lines never meet each other, options b & c are eliminated and since the lines also appear to be equidistant from each other, option d is also eliminated.

On the figure shown, DC is a _______.
1. A Ray refers to that part of a line which has 1 end point and other end has no end i.e. it is infinitely increasing at one end.
2. A line is a geometric object (collection) with infinitely increasing ends i.e. it has no end on both sides.
3. Since the given figure is that of a closed object, none of its sides can have any infinite ends.
