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.

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.
The quadrilaterals that have right angles must have a perpendicular line because that's where it meets.
Two perpendicular lines must cross at a 90 degree angle, like a plus sign: +
The walls of most buildings are perpendicular to the ground they are built on.
Objects like walls, poles, and trees must be perpendicular to the ground if the ground is flat. This ensures that they are standing upright and stable on the level surface.
A perpendicular cat must be a cat

no they dont have to be perpendicular, just square,rectangle, and isoceles trapizoid
Not necessarily. But a parallelogram with perpendicular diagonals must always be one.
The walls of most buildings are perpendicular to the ground they are built on.
diagonals are 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.
Yes, an object can still be in equilibrium even if it's acted on by two forces that are not perpendicular. The forces just need to have equal magnitudes and be in opposite directions along the same line of action. This condition ensures that the net force on the object is zero, leading to equilibrium.
