It makes sense because it is true. There are other quadrilaterals whose diagonals are perpendicular.
Take your choice of either a rhombus or a kite both of which fits the given description
No, absolutely not. Not only are they intersecting, they are perpendicular. Perpendicular means that they are at right angles to each other (90 degrees). In fact, any rhombus has perpendicular diagonals. A rhombus is any quadrilateral whose 4 sides are equal.
It is a rhombus whose diagonals are perpendicular and meeting each other at right angles.
How about a rhombus or a kite

A rectangle or a parallelogram
It is a kite or a rhombus both of which have unequal diagonals that are perpendicular to each other creating right angles.
Regular polygons whose number of sides are not even will not have any parallel sides, e.g. triangle, pentagon, heptagon.Irregular polygons of any number of sides may have no parallel sides (e.g. an irregular quadrilateral, known in the US as a trapezium).

It is a kite whose diagonals are perpendicular to each other and form 4 right angles.

It is a prismoid - a prism-like solid whose lateral faces are not perpendicular to the bases.It is a prismoid - a prism-like solid whose lateral faces are not perpendicular to the bases.It is a prismoid - a prism-like solid whose lateral faces are not perpendicular to the bases.It is a prismoid - a prism-like solid whose lateral faces are not perpendicular to the bases.
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
