A square based pyramid
Improved Answer:
It is a pentagon.
There is none. A 5 sided shape is a pentagon but that has 10 diagonals, not 2.
The formula for determining the number of diagonals in a shape is n(n-3)/2 where n=vertices, (corners or intersections of geometric shapes). For an eight sided shape we replace n with 8. 8(8-3)/2 8(5)/2 (8x5)/2 40/2=20 An octagon contains 20 diagonals. For a further example we can determine the diagonals in a shape with 5 sides: 5(5-3)/2 5(2)/2 (5x2)/2 10/2=5 A Pentagon contains 5 diagonals.
A shape with five diagonals is a hexagon. A hexagon has six sides, and the formula for calculating the number of diagonals in a polygon is given by ( \frac{n(n-3)}{2} ), where ( n ) is the number of sides. For a hexagon, substituting ( n = 6 ) results in ( \frac{6(6-3)}{2} = 9 ) diagonals. Therefore, a shape that specifically has five diagonals is a pentagon, as it fits the formula with ( n = 5 ): ( \frac{5(5-3)}{2} = 5 ).
Any quadrilateral (4-sided shape) has 2 diagonals.
35 diagonals

5(5-3)/2. That it is the formula so that shape would have 5 diagonals. n(n-3)/2 where n is the number of sides
