Parallelogram Keeping this in view, which quadrilateral must have diagonals that are congruent and perpendicular? Opposite sides are parallel and all sides are equal. Diagonals that divide each other into two equal halves are called "perpendicular bisecting diagonals" or "perpendicular bisectors." A quadrilateral whose diagonals bisect each other and are perpendicular is a: 1. A rhombus is a quadrilateral with all sides equal in length. ∠A = 45° and ∠B are consecutive interior angles, which must be supplementary. Quadrilaterals that have diagonals that bisect each other at 90 degrees are a square, a rhombus and a kite Adjacent angles are supplementary (For eg., ∠A + ∠B = 180°). Login to view more pages.

A quadrilateral is said to contain perpendicular diagonals if four 90-degree angles are formed at the intersection of these diagonal lines. In any parallelogram, the diagonals (lines linking opposite corners) bisect each other. ∴ Their diagonals are equal. We know that a parallelogram is a quadrilateral in which diagonals bisect each other. This can also be done by seeing if the diagonals are perpendicular bisectors of each other meaning if the diagonals form a right angle when the intersect. for which quadrilateral are the diagonals congruent but do not bisect each other? Since the question is about diagonals bisecting each other, which effectively means they cut each other in half, the correct answer to the question is D. Trapezoid, since the others fall into the category of the parallelogram, whose diagonals always bisect. Two angles on the same side are supplementary, that is the sum of the angles of two adjacent sides is equal to 180°. 3. He provides courses for Maths and Science at Teachoo. Question 5.

So by the same argument, that side's equal to that side, so the two diagonals of any rhombus are perpendicular to each other and they bisect each other. isosceles trapezoid Answer by Edwin McCravy(18440) (Show Source): Opposite angles of a rhombus are equal and diagonals of the Rhombus bisect each other perpendicularly. Rhombus. Only one diagonal of a kite bisects the other. The diagonals of a parallelogram bisect each other. Ex 3.4, 4 Name the quadrilaterals whose diagonals. if the diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus. Rhombus is also a parallelogram having equal sides, so rhombus have diagonals that bisect each other. If you are talking about the diagonals of a quadrilateral, the only quadrilateral that have diagonals that are perpendicular and bisect each other is a square, because a rectangle has bisecting diagonals, while a rhombus has perpendicular diagonals. A square is a quadrilateral with all sides equal in length and all interior angles right angles. It is not necessary that diagonals of all types of trapezium are equal. And the angles formed by the intersection are not always the same measure (size). square. Stays. To prove a quadrilateral is a parallelogram, you must use one of these five ways. A rectangle is a quadrilateral with two pairs of equal and parallel opposite sides and four right angles. Thus, That is, each diagonal cuts the other into two equal parts.

Two angles on the same side are supplementary, that is the sum of the angles of two adjacent sides is equal to 180°. Any isosceles triangle, if that side's equal to that side, if you drop an altitude, these two triangles are going to be symmetric, and you will have bisected the opposite side. Click to see full answer. Therefore, we have ∠A + ∠B = 180° 45° +∠B = 180° ∠B = 180°- 45° ∠B = 135° Hence the correct choice is (d). diagonals that are perpendicular to each other \[AC \perp BD\] diagonals that bisect each other.
