Does a parallelogram have diagonals that bisect each other?
They do in some parallelograms, not in others.
Is the diagonals of a parellelogram perpendicular?
That is true for some parallelograms but not all. For example, the diagonals of a rhombus, kite or square are perpendicular, but those of a rectangle or general parallelogram are not.
Will a parallelogram always sometimes or never be a square?
Some parallelograms are squares - the ones which are equiangular (have equal angles) and are equilateral (have equal side lengths). All squares are parallelograms, but only some parallelograms are squares.
There are some parallelograms which are not rectangles true or false?
yes. rectangles are just the special cases of parallelograms where the angles are all 900
Which type of quadilateral has diagonals which are not equal?
Parallelogram, trapezoid, rhombus and a kite are some of them Note that a square and a rectangle have diagonals of equal lengths
Do parallelograms have congruent diagonals?
Some of them (rectangles) do.

Some rectangles are not parallelograms?
false

What is true of all parallelograms?
The definition of a parallelogram is that it's a quadrilateral in which both pairs of opposite sides are parallel. So, that part is true about all parallelograms. Apart from that, there are some other properties that can be deduced, such as: * Opposite sides are congruent * Opposite angles are congruent * The diagonals bisect one another * The sum of the squares of the sides equal the sum of the squares of the diagonals As well as some other properties.
Do parallelograms have equal sides?
Some do, some don't. A parallelogram that has equal sides is usually called either a "rhombus" or a "square". None of the other parallelograms do.

The opposite sides of a rectangle are?
The opposite sides of a rectangle are congruent or equal. This is true because a rectangle, which is a parallelogram, must adhere to properties belonging to parallelograms. Some of these properties include that a parallelogram has two pairs of opposite sides that are congruent, and that it has diagonals that bisect one another.
Which type of quadilateral has diagonals which are not equal?
Parallelogram, trapezoid, rhombus and a kite are some of them Note that a square and a rectangle have diagonals of equal lengths
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.
What describes the angles of some parallelograms?
In all parallelograms, opposite angles are equal and the 4 interior angles add up to 360 degrees. In someparallelograms, all of the angles are 90 degrees. These parallelograms are rectangles.
