What quadrilaterals have all adjacent sides are perpendicular?

Square & Rectangle are the only two. Rhombus (diamond) & parallelogram have adjacent sides, but no 90 degree angles (not perpendicular).


Are diagonals of equal length in a parallelogram and rectangle?

the diagonal in a paralleogram is not equal but the diagonals in the rectangle are congruent this is because the opposite sides of a parallelogram and rectangle are same parallel to each other but the adjacent sides of a parallelogram is not perpendicular where as the adjacent sides of rectangle is perpendicular to each other.


Are the adjacent sides of the Parallelogram parallel?

No, the adjacent sides of a parallelogram are not parallel; rather, they are non-parallel sides that meet at an angle. In a parallelogram, opposite sides are parallel and equal in length, while adjacent sides are of different lengths and form the angles of the shape. This characteristic distinguishes parallelograms from rectangles and squares, where adjacent sides are perpendicular.

Is parallelogram a perpendicular sides?

No, a parallelogram does not have perpendicular sides by definition. A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Perpendicular sides would form a right angle, which is a characteristic of rectangles, squares, and other types of quadrilaterals, but not parallelograms.

What are names for a parallelogram that also has perpendicular sides?

A parallelogram with perpendicular sides is specifically known as a rectangle or a rhombus, depending on the lengths of its sides. If all sides are equal, it is called a square. Thus, the names for a parallelogram with perpendicular sides include rectangle and square.


Does a parallelogram have 2 adjacent sides equal?

no. Not necessarily. A rhombus is a parallelogram with equal adjacent sides. Gererally, though they will be unequal.
