Adjacent sides of a square and a rectangle are always perpendicular to each other. A kite is a quadrilateral (4 sided figure) with two pairs of adjacent sides of equal length; its diagonals are perpendicular. (The hypotenuse is the longest side of the right triangle.)

## Which of these quadrilaterals have opposite sides that are parallel?

A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel .

## What are perpendicular adjacent sides?

In a square or other rectangle, all pairs of adjacent sides are perpendicular. A right trapezoid is a trapezoid that has two pairs of adjacent sides that are perpendicular. Each of the four maltitudes of a quadrilateral is a perpendicular to a side through the midpoint of the opposite side.

## Which quadrilaterals have perpendicular lines?

Quadrilaterals with perpendicular lines have sides that meet at a right angle (90°). Some quadrilaterals also fit into another type. A square is a type of rectangle, and rectangles are also a type of parallelogram.

## Is a parallelogram parallel or perpendicular?

Parallelogram are quadrilaterals with opposite sides parallel, but adjacent sides not perpendicular. If the sides have equal lengths, then it is called a rhombus.

## 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.

## What shape has all adjacent sides perpendicular?

Rectangles are parallelograms with perpendicular 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. All the blue shapes in the image below are rectangles.

## Which types of quadrilaterals can never have perpendicular sides?

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

## What are quadrilaterals with opposite sides that are parallel?

Parallelogram are quadrilaterals with opposite sides parallel, but adjacent sides not perpendicular. If the sides have equal lengths, then it is called a rhombus. Trapezoid are quadrilaterals where one pair of opposite sides are parallel

## What are the properties of a quadrilateral rectangle?

Summary of Quadrilateral Properties Square Rectangle Rhombus Parallelogram All sides are equal Yes No Yes No Opposite sides are parallel Yes Yes Yes Yes Opposite sides are equal Yes Yes Yes Yes All the angles are of the same measure Yes Yes No No

## What are the sides of a quadrilateral ABCD?

Quadrilateral ABCD has four sides `bar”AB”, bar”BC”, bar”CD”, and bar”DA”`. It has four angles ∠A, ∠B, ∠C, and ∠D. BD and AC are the two diagonals of the quadrilateral ABCD. A quadrilateral can be named by starting at any vertex and going serially either clockwise or anti-clockwise around the figure.

## How is a quadrilateral different from a rhombus?

A quadrilateral is a rhombus if all the sides are of equal length and the two pairs of sides are parallel to each other. A kite is a special type of rhombus, in which 2 pairs of adjacent sides are equal to each other. Here we have provided some of the frequently asked questions related to properties of all quadrilaterals.
