Question
Two walls of a room intersect to form four right angles. Then the walls are
- Parallel
- Perpendicular
- Adjacent
- Opposite
Hint:
Perpendicular lines are formed when two lines meet each other at the right angle or 90o.
The correct answer is: Perpendicular
Using the theorem “If two lines are perpendicular, they will intersect to form four right angles.”
So, if two walls of a room intersect to form four right angles. Then the walls are perpendicular. It can be seen as

Final Answer:
So, if two walls of a room intersect to form four right angles. Then the walls are perpendicular. Hence, option b is correct.
Final Answer:
So, if two walls of a room intersect to form four right angles. Then the walls are perpendicular. Hence, option b is correct.
