A diagonal is normally defined as a straight line joining a vertex of a polygon with any vertex other than an adjoining vertex (lines joining a vertex to an adjoining vertex would simply be a side of the polygon). Since a triangle has only got adjoining vertices, it has no diagonals. Since there are no diagonals, they cannot bisect one another.
4 because the diagonals bisect each other at 90 degrees
No.
In a delta (triangle), the diagonals do not exist since a triangle has only three sides and three vertices. However, if you meant the diagonals of a quadrilateral, such as a parallelogram, they do bisect each other. In contrast, the diagonals of a general triangle do not bisect each other, as triangles do not have diagonals in the traditional sense.
A circle!! * * * * * Wrong: the diagonals of a circle DO bisect each other. A triangle is a possible answer.
No, for the simple reason that triangles do not have diagonals.

The diagonals of a square (which always bisect each other) are the same length.
Yes, the diagonals of a parallelogram bisect each other.
The diagonals of a square bisect each other at 90 degrees
Yes it does - they bisect each other at the exact centre of the rectangle.
Yes the diagonals of a kite bisect each other at 90 degrees.
Diagonals never bisect sides. They join the ends of sides.In a rectangle, the diagonals always bisect each other.
Not for every parallelogram. Only for a rhombus (diamond) or square will the diagonals bisect the opposite angles they connect, and diagonals are perpendicular. In rectangles, the diagonals do not bisect the angles and are notperpendicular, but they do bisect each other.
