To support the structure. But they don't have to be perpendicular.
They are not perpendicular always but in most cases they are because this is the most stable shape against the gravity of earth. Secondly it gives more room than any other shape.

Are perpendicular lines perpendicular to a third line?
Yes. Take a look at the corner of your room, where two walls meet the floor.
How can perpendicular lines affect your daily life?
If the walls in your house were not perpendicular they would probably topple over and you would no longer have a daily life for perpendicular lines to affect.
Which quadrilateral must have perpendicular lines?
The quadrilaterals that have right angles must have a perpendicular line because that's where it meets.
Two perpendicular lines must?
Two perpendicular lines must cross at a 90 degree angle, like a plus sign: +
What is a real life example of prependicular lines?
The walls of most buildings are perpendicular to the ground they are built on.
What is a perpendicular cat?
A perpendicular cat must be a cat

Do the diagonals of a rhombus must be perpendicular?
no they dont have to be perpendicular, just square,rectangle, and isoceles trapizoid
Is a quadrilateral with perpendicular diagonal a rhombus?
Not necessarily. But a parallelogram with perpendicular diagonals must always be one.
What is a real life example of prependicular lines?
The walls of most buildings are perpendicular to the ground they are built on.
A parallelogram must be a rhombus if the?
diagonals are perpendicular
Can an object be in equilibrium if the object is acted on by two forces that point in directions that are not perpendicular?
Yes. To be in equilibrium, the forces must not be perpendicular - they must point in opposite directions.
Which quadrilateral must have diagonals that are congruent and perpendicular?
The quadrilateral that must have diagonals that are congruent and perpendicular is the square. This is because its diagonals form a right angle at its center.
Can 2 line be intersecting perpendicular?
Perpendicular lines intersect at right angles. (90°) Therefore, by the definition of perpendicularity, two perpendicular lines must intersect.
