Hi guys
I'm a little confused as to whether we should consider the properties of a kite when dealing with quadrilaterals. For example:
Is quadrilateral ABCD a Rhombus?
(1) Line segments AC and BD are perpendicular bisectors of each other
(2) AB = BC = CD = AD
The official answer is as follows:
Statement 1 - SUFFICIENT: The diagonals of a rhombus are perpendicular bisectors of one another. This is in fact enough information to prove that a quadrilateral is a rhombus
Statement 2 - A quadrilateral with four equal sides is by definition a rhombus
What I don't get is that the question mentions it is a quadrilateral, not a parallelogram. In this case, how can we eliminate the possibility that it could be a kite as well in Statement 1?
Statement 1 says the diagonals are perpendicular bisectors of each other which means that they intersect each other at mid points and form 90 degree angles. It is not possible that they are in the shape of an asymmetric kite. Figure 1 is not possible. Only figure 2 is possible. In figure 2, all sides will be equal.

This is an interesting post. So to be clear, the distinction is this
1. The diagonals of a kite INTERSECT each other, but we don't consider them as bisectors b/c the diagonals are not split evenly
2. The diagonals of a rhombus are PERPENDICULAR BISECTORS (bisection b/c diagonals are split evenly into two)
3. The diagonals of a rectangle are NON-PERPENDICULAR bisectors (b/c the bisection does not form 90 degree angles), but in the case of a square the bisectors ARE perpendicular bisectors.
Bunuel is this accurate?
