There is not a shape with the most corners. You could always "one-up" the last shape. It is like with numbers, there is not a highest number, but instead there is infinity.
Rectangle
There is no such thing. For any shape, you can always imagine a shape that has one more corner.
the vertices are the corners to the shape, so you count the corners to whatever shape.
That's impossible, because if a shape has sides, then it means it has corners, and vice versa.
No such shape exists.
triangle
There is no such thing. For any shape, you can always imagine a shape that has one more corner.
The shape with the fewest corners, ie the sphere.
a heptagon has 7 corners and a octagon has 8 corners .
A shape that has 12 corners is called a dodecagon. This shape not only has 12 corners but alsoÊ12 sides.
No shape can have two corners
An heptagon has 7 corners and 7 sides whereas an octagon has 8 corners and 8 sides
The shape with 8 corners is called an octagon.
A sphere has no corners and no edges
the vertices are the corners to the shape, so you count the corners to whatever shape.
the corners
That's impossible, because if a shape has sides, then it means it has corners, and vice versa.
No such shape exists.
