true
The missing word is "bisect".
Most quadrilaterals do not.
A quadrilateral is a parallelogram if and only if its diagonals bisect each other (this should be in any geometry book)
Yes, any quadrilateral has diagonals.
A quadrilateral has 2 diagonals.
A Quadrilateral has two diagonals. IF the quadrilateral is a rectangle, then the two diagonals are equal in length.
A rectangle is an example of a quadrilateral where the diagonals are congruent and bisect each other. However, a kite is a quadrilateral that can also have congruent diagonals, but they do not bisect each other. In a kite, one diagonal bisects the other at a right angle, while the other diagonal remains unequal in length. Therefore, while both shapes can have congruent diagonals, only the rectangle has diagonals that bisect each other.
If the diagonals of a quadrilateral are perpendicular to each other, then the quadrilateral is a square.Or a kite.
A quadrilateral has 2 diagonals. It does not matter whether it is convex or not.
2 diagonals
A quadrilateral has two and only two diagonals. That's the maximum and also the minimum. If it has more or fewer than two diagonals, it's not a quadrilateral.
quadrilateral
Sure, a square is a rectangle and the diagonals of a square are perpendicular.
It has two diagonals
