No. They are equal in only a few circumstances.
Its diagonals are equal in length
No as for example the diagonals of a rectangle are equal in length whereas they are not equal in length in a parallelogram
A parallelogram.
No
The diagonals of any parallelogram (square, rhombus, rectangle, rhomboid) bisect each other. The difference is the the diagonals are equal in length for a square and rectangle, and not equal for a rhombus or rhomboid (oblique diamond).
Its diagonals are equal in length
The diagonals of a parallelogram are congruent (equal in length) and bisect each other.
the sides that are parallel of each other are equal. * * * * * True, but that was not the question! In general, the diagonals are not of equal length.
yes
They are of equal length.
No as for example the diagonals of a rectangle are equal in length whereas they are not equal in length in a parallelogram
yes it is it is a parallelogram of its angles is right or The two diagonals are equal in length
An isosceles trapezoid will have diagonals of equal length but will never contain right angles by definition. A square and rectangle will have diagonals of equal length but will contain 4 right angles. A rhombus and any other parallelogram that does not contain right angles will not have diagonals of equal length.
A parallelogram.
If the parallelogram happens to also be a rhombus (i.e. has all sides equal in length) then yes, otherwise no.
Yes. Other things about parallelograms: -opposite sides are equal in length. -opposite angles are equal in length. -diagonals bisect each other.
No, they are not.
