It's diagonals, and opposite sides must be parallel and congruent.
A parallelogram has adjacent equal sides. Diagonals of a parallelogram bisect each other,Opposite sides of a parallelogram are parallel and will never intersect. The area of a parallelogram is twice the area of a triangle created by one of its diagonals. Any line through the midpoint of a parallelogram bisects the area.
A quadrilateral whose diagonals bisect each other at right angles is a rhombus. each other at right angles at M. So AB = AD and by the first test above ABCD is a rhombus. 'If the diagonals of a parallelogram are perpendicular, then it is a rhombus
Not necessarily.
Parallelogram
not necessarily. because the diagonals of a trapezium also bisect each other and it is not a parallelogram. in order for the quadrilateral to become a parallelogram, the opposite angles of it must be equal, and the opposite sides must be equal too. the angles formed by the two diagonals( four in number) also must be equal if they are opposite angles not alternating angles.that's it pal
In a parallelogram opposite sides are parallel to each other.
The diagonals of a parallelogram do not intersect each other at right angles and so therefore they aren't perpendicular to each other.
No.
Yes every parallelogram has bisecting diagonals
A parallelogram is a quadrilateral (4-sided figure) with both pairs of opposite sides parallel. That's usually the primary definition. There are properties common to all parallelograms: opposite sides are congruent, opposite angles are congruent, and diagonals bisect each other. Other special parallelograms have additional properties. A rectangle is a parallelogram with four right angles and its diagonals are congruent. A rhombus is a parallelogram with four congruent sides. Its diagonals are perpendicular and each diagonal bisects two angles of the rhombus. A square is a parallelogram as well. It has four right angles and four congruent sides, so it is also a rectangle and a rhombus. How's that for confusing???
No, they do not. Only the longer diagonal bisects the shorter diagonal.
The diagonals of a parallelogram are congruent (equal in length) and bisect each other.
