What do parallelograms and rectangles have in common?
Parallelograms and rectangles are both types of quadrilaterals, meaning they each have four sides. Both shapes have opposite sides that are parallel and equal in length. Additionally, the angles in rectangles are all right angles (90 degrees), while parallelograms have opposite angles that are equal but are not necessarily right angles. This means that all rectangles are parallelograms, but not all parallelograms are rectangles.
What is a parallelogram where all 4 sides are equal and the opposite sides are parallel?
All "parallelograms" have opposite sides that are parallel. If all four sides have an equal length and the angles are not all right angles, it is a rhombus. If there is any right angle, then they are all right angles and the parallelogram is a square.(note : it is not possible for a quadrilateral to have four equal sides without being one of these parallelograms.)
Why are all rectangles examples of parallelograms but all parallelograms are not rectangles?
To be a parallelogram, the figure needs both sets of opposite sides to be parallel. A rectangle needs to have four right angles. This means the rectangle has to be a parallelogram. However, you can have opposite sides parallel without having right angles, as long as opposite angles are equal to each other,
Does a paralellelogram have 4 right angles and opposite sides of equal lenghth?
A parallelogram always has opposite sides of equal length. Its 4 angles may be right angles, but in most parallelograms they're not. If they are, then that parallelogram is also called a 'rectangle'.
What quadrilateral has 4 sides its opposite sides are parellel and it has no right angles?
The quadrilateral you are describing is a parallelogram. In a parallelogram, opposite sides are parallel and equal in length, but it does not necessarily have right angles; the angles can be acute or obtuse. Examples of such parallelograms include rhombuses and non-right-angled rectangles.

What relations among the sides and angles of rectangles are also true of parallelograms?
Opposite sides are parallel and opposite angles are equal

What angle property do parallelograms have?
Opposite angles/sides are equal.

What are the 5 properties of parallelograms?
If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Opposite angles are congruent. Opposite sides are congruent. Consecutive angles are supplementary.
Can parallelograms have right angles?
Yes, it can... but does not have to. A parallelogram is a four-sided plane figure with opposite sides parallel. So as long as it has opposite sides that are parallel, it is a parallelogram.
Do all parallelograms have diagonals which bisect?
Yes; all parallelograms have diagonals that bisect each other. Other properties of parallelograms are: * The opposite sides are congruent. * The opposite sides are parallel. * The opposite angles are congruent.
What shape is a square but not a parelellogram?
No shape is a square but not a parallelogram as all squares are parallelograms: All parallelograms have opposite sides parallel and of equal length, and opposite angles are equal. All squares have opposite sides that are parallel and of equal length, and opposite angles are equal; thus all squares are parallelograms. However, all squares also have all angles equal to 90o and all four sides equal, but some parallelograms have angles not all 90o and/or not all four sides of equal length; thus not all parallelograms are squares.
How many sides are there in parallelogram?
Parallelograms have 4 sides, it is a quadrilateral with the opposite sides parallel, and the opposite angles are congruent.4
