Rectangles have congruent adjacent angles.
A parallelogram.Types of parallelogram:Rhomboid - A quadrilateral whose opposite sides are parallel and adjacent sides are unequal, and whose angles are not right anglesRectangle - A parallelogram with four angles of equal sizeRhombus - A parallelogram with four sides of equal length.Square - A parallelogram with four sides of equal length and four angles of equal size (right angles).
No, a rectangle has opposite side which are equal in length.
A rectangle with 4 equal sides and angles is often called a square.
you can prove any one of these statements to prove that quadrilateral is a rectangle: -- Opposite sides are parallel and any one angle is a right angle. -- Opposite sides are equal and any one angle is a right angle. -- All four angles are right angles. -- Adjacent angles are complementary, and one of them is a right angle. -- Opposite sides are either equal or parallel, and area is equal to the product of two adjacent sides. -- Diagonals are equal.
The main difference between a rectangle and a parallelogram that makes rectangle a special case of the parallelogram is the fact that all the angles of a rectangle are equal to 90 degrees. This is not the case in a parallelogram because the adjacent angles are only supplementary to each other.
A quadrilateral with equal adjacent angles is called a rectangle. In a rectangle, each angle measures 90 degrees, and adjacent angles are equal. This property distinguishes rectangles from other quadrilaterals, such as rhombuses or parallelograms, where angles may not be right angles.
Rhombuses are paralellograms. Also, they're what you might call a diamond.* * * * *Not a particularly useful answer since a rectangle is also a parallelogram. The two differences are:all the sides of a rhombus are of equal length while in a rectangle opposite sides are equal but adjacent sides are usually not equal (if they are, then the shape is a square);all the angles of a rectangle are right angles while in a rhombus opposite angles are equal but adjacent angles are usually not equal (if they are, then the shape is a square).
A Square and a Rectangle are both Parallelogram.Square:A square is a parallelogram in which adjacent sides are equal and one of its angles is 90o.Rectangle:A Rectangle is a parallelogram in which one of its angles is 90o.
Rhombus = 4 equal sides Rectangle = 4 equal angles Square = 4 equal sides and 4 equal angles Rhomboid = unequal adjacent sides and angles
A rectangle. If there are equal adjacent sides it's a square.It is a square or a rectangle both of which are 4 sided quadrilaterals
This is a rectangle.
You have described a rectangle.
A rectangle
A rectangle (that is not a square).
a rectangle
A parallelogram is a four-sided figure with opposite sides of equal length and angles not equal to 90 degrees (otherwise it would be a rectangle). Diagonally opposite angles will be equal, and adjacent angles will add up to 180 degrees.
No. A rectangle has all angles equal to 90o; a rhombus has opposite angles equal but they do not need to be 90o; thus all rhombuses are not rectangles. All rectangles have four equal angles and opposite sides of equal length, all four sides need not be the same length; a rhombus has all 4 sides of equal length; thus all rectangles are not rhombuses either.
