are consecutive angles supplementary in a rhombus?

Corollary 4: Two consecutive angles in a rhombus are supplementary and opposite sides are parallel. Proof: By considering , we see that Now, the measure of angle BDC is and the measure of angle DCA is so the sum of these two consecutive angles is 180 degrees; thus, they are supplementary.

The rhombus has the following properties: 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.

Both parallelogram and rhombus are quadrilateral, whose facing sides are parallel, opposite angles are equal, the sum of the interior angles is 360 degree. A rhombus itself is a special kind of parallelogram. Therefore, it can be said that every rhombus is a parallelogram, but the reverse is not possible.

Diagonals of a rhombus In any rhombus, the diagonals (lines linking opposite corners) bisect each other at right angles (90°). That is, each diagonal cuts the other into two equal parts, and the angle where they cross is always 90 degrees.

It is known that both the rhombus and the parallelogram are considered as the quadrilateral as they have four sides. The opposite faces of a parallelogram are parallel so that the opposite angles of the shape are also equal. But in rhombus, all the four sides are of equal measure.

Basic properties Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides. ... Opposite angles of a rhombus have equal measure. The two diagonals of a rhombus are perpendicular; that is, a rhombus is an orthodiagonal quadrilateral. Its diagonals bisect opposite angles.

Basic properties Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides. Using congruent triangles, one can prove that the rhombus is symmetric across each of these diagonals.

If the diagonals of a quadrilateral are perpendicular, then it is a rhombus. False – diagonals don't have to be congruent or bisect each other. The diagonals of a rectangle bisect its angles. ... A kite with all consecutive angles congruent must be a square.

If the diagonals of a parallelogram are congruent then the parallelogram is a rectangle. if a parallelogram is a rhombus, then each diagonal bisects a pair of opposite angles. ... if one pair of consecutive sides of a paralleloram are congruent, the parallelogram is a rhombus.
