Two. If you start from any vertex, the lines to either of the two adjacent vertices will be one of the sides of the original shape. Only the line joining it to the opposite vertex will be a new line - a diagonal. Four vertices might therefore suggest four such lines but remember you're counting each line twice - once from each of its end. From any vertex, you can have only one diagonal - to the next but one vertex. Lines to the next vertex, on either
A rhombus.
a square
The shape you are describing is a rhombus. A rhombus has four sides of equal length, but its diagonals are not equal; instead, they bisect each other at right angles. This distinguishes it from a square, which has both equal sides and equal diagonals.
Any quadrilateral (4-sided shape) has 2 diagonals.
Only one.
There are 7*(7-3)/2 = 7*4/2 = 14 diagonals.

Nope, in order for the diagonals to be perpendicular the shape must be a square (which I guess is a type of rectangle :). The diagonals will cross, but not at a 90degree angle, unless the sides are of equal length.Not unless the rectangle has 4 equal sides, making it a squre.
A diamond shape has four sides, so it is essentially a quadrilateral. The formula for calculating the number of diagonals in a quadrilateral is (n)(n-3)/2, where n is the number of sides. In this case, n = 4, so the calculation would be (4)(4-3)/2 = 2 diagonals. Therefore, a diamond shape could have 2 diagonals drawn within it.
