The rigidity of the triangle derives from the fact that you cannot change any angle in a triangle without also changing the length of at least one side; in any other type of polygon, it is possible to alter the angles of the polygon without changing the lengths of the sides. So if you have a physical object in the form of a triangle, the sides are not going to change their length unless you break them. Other shapes can fold up, but triangles won't.

A polygon with any number of sides can have a 156 degree angle, as can most non-polygonal plane shapes.
What is the most used shape for a structure a square or a triangle?
Square
What shape has a triangle as a base and it has 3 rectangular faces?
most likely a triangular prism
Which shape is found most often within a structure?
Triangle. Its the strongest geometric shape

The most rigid shape that you can make out of straight pieces is the triangle.
What is the most common shape of tunnels?
An inverted U shape is the most common tunnel shape as this is the strongest.
What geometric shapes are strongest or most stable in bridge design?
triangle

How can you strengthen a load bearing horizontal beam that is supported only at the ends?
you have to change the beam to another one that could be hollow and most likely change it to a triangle beam because it is the strongest shape
What is the most rigid shape?
It's The Triangle
What is the shape with and 156 degree angle?
A polygon with any number of sides can have a 156 degree angle, as can most non-polygonal plane shapes.
Is a square stronger than a rectangle?
yes because they are more compact and balanced. The strongest shape is a triangle, so putting two obtuse triangles together to form a square is how most structures are created to be stable.
What is the most used shape for a structure a square or a triangle?
Square

Your shape is a triangular octagon. * * * * * What on earth is that shape? The most likely answer is an octogonal pyramid.
What is the most structural sound shape?
Usually a triangle-esque figure.
