Yes, unless it's a square, which is a special case of rectangularity.
Is it not a parallelogram in which the adjacent sides are of different/unequal lengths ?
Here are a few: Rectangle, Square, Polygon, four sided shape, A shape with Unequal Adjacent Sides
A rectangle has four sides, and each side has two adjacent sides. Therefore, each side of the rectangle is adjacent to two others. In total, there are eight pairs of adjacent sides if you consider each side's adjacency individually.
In a parallelogram, adjacent sides are not equal; rather, opposite sides are equal in length. This means that if one pair of opposite sides is equal, the other pair will also be equal, but the adjacent sides can be of different lengths. For example, in a rectangle (which is a type of parallelogram), adjacent sides can be unequal, while in a rhombus, all sides are equal.
Rhombus = 4 equal sides Rectangle = 4 equal angles Square = 4 equal sides and 4 equal angles Rhomboid = unequal adjacent sides and angles
Is it not a parallelogram in which the adjacent sides are of different/unequal lengths ?
A rectangle is a plane figure with four straight sides and four right angles. Generally considered to have unequal adjacent sides to differ them from squares.
Here are a few: Rectangle, Square, Polygon, four sided shape, A shape with Unequal Adjacent Sides
Adjacent sides of a rectangle are perpendicular.
adjacent sides of a rectangle are the sides that are next to each other. :D
A parallelogram with adjacent sides of unequal length is known as an oblique parallelogram. In this type of parallelogram, the opposite sides are still parallel and equal in length, but the adjacent sides are not. The angles between the unequal sides are also not right angles, making it different from a rectangle or square. The area of an oblique parallelogram can be calculated using the formula: base x height.
A parallelogram with unequal adjacent sides
A rectangle has four sides, and each side has two adjacent sides. Therefore, each side of the rectangle is adjacent to two others. In total, there are eight pairs of adjacent sides if you consider each side's adjacency individually.
Rhombus = 4 equal sides Rectangle = 4 equal angles Square = 4 equal sides and 4 equal angles Rhomboid = unequal adjacent sides and angles
A quadrilateral that is not a rectangle is a kite. A quadrilateral is a figure that has four straight sides. A rectangle has opposites sides that are parallel and of equal measurement. However, a kite is a quadrilateral by definition but is unlike a rectangle because it has pairs of equal adjacent sides.
Adjacent sides are sides that are immediately side by side. They are sides that form or subtend an angle.
Adjacent sides are two sides that meet to make an angle, so yes.
