What shape has 5 sides and 2 diagonals?
There is none. A 5 sided shape is a pentagon but that has 10 diagonals, not 2.
How many diagonals does a shape with 8 sides have?
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.
What shape has 2 diagonals?
Any quadrilateral (4-sided shape) has 2 diagonals.
How many diagonals does a 10 sided shape have?
35 diagonals
How many diagonals in a dodecagon have?
There are 54 diagonals in a 12 sided shape

How many diagonals does a shape with 5 sides have?
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

What shape has all diagonals inside?
A convex shape.
Which quadrilaterals have diagonals that intersect at right angles outside the shape?
Only a chevron has diagonals intersecting outside the shape. The diagonals of a symmetric chevron will intersect at right angles.
What shape has perpindicular diagonals?
square

How many diagonals are there in a 25 sided shape?
There are 275 diagonals in a shape with 25 sides. The formula is n*(n-3)/2
