In triangle ABC one side equal
and two sides equal

We are given a prism whose base is square with sides 8 in and height 12 in.
If we take cross section through vertices A, B and C
We will get a cross section as triangle.
In triangle ABC, sides are AB, BC and AC
AB is diagonal of top square whose side 8 in.

AC is face diagonal of front face.

BC is face diagonal of right face.

AC=BC≠AB
Hence, In triangle ABC one side equal
and two side equal

p 0.00391
we find that p value is 0.00391 <0.05
Hence we reject null hypothesis
