both are parallel
The diagonals of a parallelogram are parallel and the same length.
If the diagonals are cong. then the figure is a rectangle.
There are 170 diagonals
Diagonals connect corners of a figure. If you try to connect two corners of a three sided figure, the lines you draw will exactly mimic the sides of the figure. Because of this, a three sided figure has no diagonals.
Yes.Yes.Yes.Yes.
Not in our Universe they're not!
Because the diagonals in a square are at right angles to one another!
A 16 sided polygon has 104 diagonals
noNo, the diagonals of a rhombus are perpendicular to each other.Unless the rhombus is regular (and called a square) the diagonals are of different lengths.
rectangles and squares
A rhombus is perpendicular * * * * * No, it is not. A rhombus is a four sided plane figure which has two pairs of parallel sides. It is, therefore, a parallelogram. The only thing that is perpendicular in a rhombus is that its diagonals bisect one another at right angles.
