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.
