Answer:
Step-by-step explanation:
Suppose x and y are nonzero vectors in an inner product space.
Let us assume that x and y are orthogonal
i.e. innter product is 0.
This implies dot product of x and y is 0
Then x.y =0
i.e. 
Proved
Converse part:
Let 
Square also would be equal

Hence inner product of x and y is 0
