# Do all rectangles have perpendicular and parallel sides?

## Do all rectangles have perpendicular and parallel sides?

As we mentioned before, right triangles have perpendicular sides, rectangles have both perpendicular and parallel sides, but other quadrilaterals might not. A regular pentagon has no parallel or perpendicular sides, but a non-regular pentagon might have parallel and perpendicular sides.

How do you know if adjacent sides are perpendicular?

Perpendicular lines are lines in the same plane that intersect at a right angle. The opposite sides of a rectangle are parallel, and the adjacent sides are perpendicular.

How many perpendicular sides does a rectangle have?

There are 4 right angles, but 2 pairs of perpendicular lines.

### What are the adjacent sides of a rectangle?

The opposite sides of a rectangle are parallel and equal. The adjacent sides of the rectangle are always perpendicular to each other.

Is a parallelogram parallel or perpendicular?

Parallelogram are quadrilaterals with opposite sides parallel, but adjacent sides not perpendicular.

What does it mean if adjacent sides are perpendicular?

## What shape has adjacent sides that are perpendicular?

Rectangles are parallelograms with perpendicular sides Rectangles have four straight sides. Each pair of opposite sides is parallel, and adjacent sides are perpendicular. This means that every angle in a rectangle is a right (90∘) angle.

Does acute triangle have perpendicular sides?

Right triangles can come in all sorts of shapes, but they all have that corner, where the right angle sits. You can see that in all the triangles, the right angle has the two sides that are perpendicular to one another. The other two angles are acute angles (meaning they’re less than 90 degrees).

Do rectangles have perpendicular diagonals?

The diagonals are perpendicular bisectors of each other. The rectangle has the following properties: All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite sides are congruent, and diagonals bisect each other). All angles are right angles by definition.

### Does triangle have perpendicular lines?

The perpendicular bisectors of a triangle are lines passing through the midpoint of each side which are perpendicular to the given side.

What shape has perpendicular lines?

The trapezium also has perpendicular lines, which have formed two right angles. They are marked with the small square symbol in the corners. Example 2 This parallelogram has no right angles so no perpendicular lines, but it does have two sets of parallel lines.
