What are the quadrilaterals whose diagonals cross at right angles?
They are either kites or (if the diagonals bisect each other) rhombuses.
What is quadrilateral whose diagonals are perpendicular to each other but unequal?
It is a kite or a rhombus both of which have unequal diagonals that are perpendicular to each other creating right angles.
Is a parallelogram symmetrical?
In short, yes. A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle. And, since a square is a degenerate case of a rectangle, both squares and rectangles are special types of parallelograms.
What are angles whose measures have a sum of 90 degrees?
Two angles the sum of whose measures is 90 degrees are complimentary angles.
A quadrilateral whose name means right angle?
rectangle
In which parallelogram are the diagonals perpendicular?
It is a rhombus whose diagonals are perpendicular and meeting each other at right angles.
Which quadrilaterals have diagonals that bisects each other?
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
What are the quadrilaterals whose diagonals cross at right angles?
They are either kites or (if the diagonals bisect each other) rhombuses.
Why is rectangle called the special parallelogram?
It is the parallelogram whose angles are right angles.
What are the two names of quadrilaterals whose diagonals cross at right angles?
wxyz
What is a quadrilateral with all of whose angles are right?
A quadrilateral having four right angles is called a rectangle.
Quadrilateral whose name literally means right angles?
rectangle
What rectangle whose are all right angles and whose sides are all congruent?
A square one.
Where did the name rectangle come from?
It is a quadrilateral, all of whose vertices are right angles. Recht = German for right so rechtangle -> rectangle.
Whose diagonals are congruent?
square, rectangle and an isosceles trapezoid
What quadrilaterals have diagonals that bisect the angels of the quadrilateral?
Rhombus and square are the only quadrilaterals whose diagonals bisect the angles of the quadrilateral. In both these quadrilaterals, the diagonals intersect at right angles, dividing each angle into two equal parts.
What is quadrilateral whose diagonals are perpendicular to each other but unequal?
It is a kite or a rhombus both of which have unequal diagonals that are perpendicular to each other creating right angles.
