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. ...

Is a pentagon a rigid structure?
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. ...

What is the difference between the pentagon and the pentagon building?
They are both the same. Pentagon is just a shorter way of saying the pentagon building. As for if you meant the shape pentagon, it is called the pentagon because it's shape is a pentagon. ...

What is a rigid shape?
A rigid shape is when you cant push/pull on it and make it turn into a different shape. You can make shapes rigid by adding "braces", which are lines that you put inside the shape to make triangles (which are rigid). For instance, a square is not rigid. To make it rigid, you would put a brace inside diagonally. This would create TWO triangles, and therefore, rigid. ~xDragonx ...

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...
