Question

Look at the shapes given below and state these are polyhedra using Euler’s formula.

✓

Answer

In the give figure, we have. Faces $(F) = 2$, verties $(v) = 1$ and edges $(E) = 0$.
On putting these values in Euler's formula,
we get. $F + V - E = 2 \Rightarrow 2 + 1 - 0 = 2$ $\Rightarrow 3\neq2$
Hence, these valus do not satisfy the Euler's formula. So, it is not a polyhedra.
