The diagonals of a parallelogram are sometimes congruent. The diagonals of a rhombus are always perpendicular. The consecutive angles of a parallelogram are never complementary. A square is always a rhombus.

All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary). All sides are congruent by definition. The diagonals bisect the angles.

Diagonals of a parallelogram In any parallelogram, the diagonals (lines linking opposite corners) bisect each other. That is, each diagonal cuts the other into two equal parts. In the figure above drag any vertex to reshape the parallelogram and convince your self this is so.

In a parallelogram, the diagonals are equal. In a parallelogram, the diagonals bisect each other. In a parallelogram, the diagonals intersect each other at right angles. In any quadrilateral, if a pair of opposite sides is equal, it is a parallelogram.

If the diagonals of a parallelogram are both perpendicular and congruent, then the special quadrilateral is rhombus. A Rhombus is a flat shape having for equal sides. A rhombus looks like a diamond, where both sides have the same length. The opposite sides are identical, and the angles opposite are equal.

Diagonal of Parallelogram Formula A parallelogram is a quadrilateral whose opposite sides are parallel and equal. The opposite sides being parallel and equal, forms equal angles on the opposite sides. Diagonals of a parallelogram are the segments which connect the opposite corners of the figure.

Theorem 16.5: If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.

The diagonals of a parallelogram are not of equal length. They bisect with each other at the point of intersection with equal sides across the point of intersection. This can be proved using the ASA criterion as well. When we divide the parallelogram through two diagonals, we see that four triangles are formed.

All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary). All sides are congruent by definition. The diagonals bisect the angles. The diagonals are perpendicular bisectors of each other.

The diagonals of a parallelogram are represented by vector R1 = 3i + 2j- 7k and vector R2 = 5i +6j -3k. ... In a parallelogram, the longer diagonal corresponds to A + B, and the shorter diagonal corresponds to A - B. Let us find | R¹| and | R²|, where R¹ and R² are the two diagonals of the parallelogram.

The opposite angles of a parallelogram are congruent. ... The diagonals of a parallelogram are sometimes congruent. The diagonals of a rhombus are always perpendicular. The consecutive angles of a parallelogram are never complementary.

Opposite sides of a parallelogram are parallel (by definition) and so will never intersect. The area of a parallelogram is twice the area of a triangle created by one of its diagonals.

Parallelogram Theorem #1: Each diagonal of a parallelogram divides the parallelogram into two congruent triangles. Parallelogram Theorem #2: The opposite sides of a parallelogram are congruent. ... You can show that alternate interior angles are congruent and hence lines are parallel for this part of the proof.

Opposite sides are parallel to each other. The diagonals are congruent. The diagonals are perpendicular to and bisect each other. A square is a special type of parallelogram whose all angles and sides are equal.

THEOREM Converse: If a parallelogram has diagonals that are perpendicular, it is a rhombus. A square is a parallelogram with four congruent sides and four right angles. This definition can also be stated as: A square is a quadrilateral that is also a rectangle and a rhombus.

No, as a general rule the diagonals of a parallelogram do not bisect each other at right angles. The definition of a parallelogram is a four-sided polygon with opposite sides parallel and equal in length. ... For all parallelograms that are not squares, the diagonals do not intersect at right angles.
