square,
It is always true that a parallelogram:is a four-sided shape (a quadrilateral)has opposite sides that are parallel to each other and of the same lengthhas opposite internal angles that equal one anotherhas diagonals that bisect one anotherhas a rotational symmetry of 2.
triangle
octagon
There are 275 diagonals in a shape with 25 sides. The formula is n*(n-3)/2
Trapezoid.
Only for a square or rhombus (diamond shape). The diagonals of a rectangle bisect each other, but are not perpendicular and do not bisect the opposite angles they join.
Rectangle
The diagonals of a rectangular shape will only bisect opposite angles if, in fact, the shape is a square. Otherwise they will not bisect them.
square,
A trapezoid Trapezoid - 2 congruent diagonals that do not bisect each other. No right angles and has 1 pair of opposite parallel sides.
Star
Because a rhombus is a regular four-sided shape.
No - only one of the diagonals bisects the angles of the shape.

Kite* * * * *No. On two counts:Only one of the diagonals is bisected.They meet at right angles.The correct answer is a parallelogram.
