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.

Why is a pentagon a rigid shape?
This is a misguided question since a pentagon is NOT a rigid shape.
Is the shape of a house 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.
What is the area of the figure with 25cm 7cm 14cm 12cm 12cm?
Since there are five numbers given it is assumed that the figure in question is a pentagon. Unfortunately, a triangle is the only polygonal shape that is rigid. A pentagon, with all five sides of known lengths is not rigid - it can be flexed in the same way that a square can be flexed into a rhombus. The area of a rhombus can take any value from 0 up to the value of the square: the exact value is indeterminate. Similarly for a pentagon.
What does the military pentagon have to do with geometry?
The military Pentagon is named after the geometric shape, the pentagon, due to its architectural structure. The Pentagon building itself is a five-sided polygon with five equal sides and five equal angles, representing a classic example of a pentagon shape in geometry. However, apart from its shape, there is no direct connection between the military Pentagon and the study of geometry.
Is the prefix pent used in pentagon Latin or Greek?
Its from the greek word pente (πεντε) meaning five (5). Also the other part of pentagon is greek. It means ''angle''. Pentagon means (a structure) that has five angles.
Is a pentagon shape in a pentagon shape a rigid shape?
yes a pentagon is a rigid shape * * * * * I am afraid that it is not.
Why is a pentagon a rigid shape?

Is a pentagon rigid?
No. A triangle is the only rigid polygon.
What is the difference between a structure that is rigid and one that is flexible?
The difference between a structure that is rigid and one that is flexible is that the rigid structure will not bend or flex when force is applied. A structure that is rigid cannot flex.
Identify the structures that comprise an animal cell?
An animal cell's structure is flexiable while a plants cell's structure is rigid
What name is given to the rigid structure found outside the plasma membrane that surrounds and supports the bacterial cells?
The cell wall is a rigid supporting structure.
How many rigid parts are in acetylsalicylic acid?
There are two: the c double bonded to o parts and the ring structure.
A plant cell has a structure that keeps its shape very rigid What structure has this purpose?
Cell wall
What is a rigid structure surrounding the cell memebrane?

Why are brains squishy?
Because they are 80% water and have no rigid structure
