A diagonal is a line joining two nonconsecutive vertices of a polygon or polyhedron.
An isosceles trapezoid will have diagonals of equal length but will never contain right angles by definition. A square and rectangle will have diagonals of equal length but will contain 4 right angles. A rhombus and any other parallelogram that does not contain right angles will not have diagonals of equal length.
Figures that do not always have congruent diagonals include trapezoids and general quadrilaterals. In a trapezoid, for instance, the diagonals can be of different lengths depending on the angles and side lengths. Similarly, most irregular quadrilaterals lack any specific properties that guarantee congruent diagonals. Only specific types of quadrilaterals, such as rectangles and squares, have congruent diagonals by definition.
A undecagon has 44 diagonals. A dodecagon has 54 diagonals. An octagon has 20 diagonals. A heptagon has 14 diagonals.
It has 1,345,890 diagonals
In a heptagon there is 14 diagonals
A kite has two pairs of adjacent sides congruent. The diagonals intersect at right angles and bisect one set of angles.
9 diagonals
It has 0 volume diagonals and 6 face diagonals hence the total number of diagonals are 6
