This is a misguided question since a pentagon is NOT a rigid shape.

Is the "shape of a house" like a child's silhouette of a house? A horizontal base with vertical uprights at each end, and a roof consisting of two sloped lines. That is a pentagon and it is not a rigid shape. The only polygon that is rigid is a triangle.
A pentagon is a 5 sided geometrical polygon whose 5 interior angles add up to 540 degrees. A pentagon is not a rigid structure unless the angles of the pentagon are "reinforced" or "fixed" so that they can't change. The only naturally rigid shape is a triangle. That is why many structures such as bridges have girders arranged in triangle formations.
