So if opposite sides of a quadrilateral are parallel, then the quadrilateral is a parallelogram. Whereas, a rhombus does not always require congruent interior angles, i.e., 90 degrees. 3 A parallelogram must be a rectangle when its 1) diagonals are perpendicular 2) diagonals are congruent 3) opposite sides are parallel 4) opposite sides are congruent 4 A parallelogram is always a rectangle if 1) the diagonals are congruent 2) the diagonals bisect each other 3) the diagonals intersect at right angles 4) the opposite angles are congruent 5 In parallelogram ABCD, diagonals ACand BD Answer. Right Angles in Parallelograms Although students are taught that four-sided figures with right angles -- 90 degrees -- are either squares or rectangles, they are also parallelograms , but with four congruent angles instead of two pairs of two congruent angles . Rectangle, trapezoid, quadrilateral. That is, each diagonal cuts the other into two equal parts. D. Diagonals are congruent. The diagonals of a parallelogram bisect each other. One such property is that the diagonals of a rectangle are congruent. Notice the behavior of the two diagonals. which could be the parallelogram Trapezoid Kite Rhombus Rectangle. Answers (2) Chisisi 11 December, 09:39. Look for and make use of structure. rectangle. 0. And so we have proven that in parallelograms, the two pairs of opposite angles are congruent.

Get an … The diagonals of a parallelogram bisect each other. Let's take triangles ΔAOD and ΔCOD. Tags: Question 3 . We have one common side - OD, and since the diagonals are perpendicular, m∠AOD = m∠COD=90°, and so ∠AOD ≅ ∠COD. If we have a quadrilateral where one pair and only one pair of sides are parallel then we have what is called a trapezoid. The diagonals of a parallelogram bisect each other (and conversely: if the diagonals of a quadrilateral bisect each other, it is a parallelogram). Opposite angles are congruent. A square is … A parallelogram is a quadrilateral that has opposite sides that are parallel. There are six important properties of parallelograms to know: If we have a parallelogram where all sides are congruent then we have what is called a rhombus. Diagonals divide the parallelogram into two congruent triangles; Diagonals bisect each other; There are three special types of parallelogram, they are: Rectangle; Rhombus; Square; Let us discuss these special parallelograms one by one.
