I'm pretty sure it refers to the fact that a triangle, when in two dimensions, can't collapse. That is, there's no way to change the actual shape of a triangle (other than rotating or moving it) without changing the lengths of the sides.

Look at the image at the above link. Notice how when the square collapses into a parallelogram, the sides still stay the same lengths, but the angles change. That's not possible with a triangle-if the angles change, so do the lengths of the sides. Therefore, a triangle is rigid.
(To help visualize this better, picture yourself holding a square frame with hinges at the corners, so it can be bent. It would be easy to bend it into a parallelogram. However, picture the same, only with a triangle. It can't be done.

What is lateral rigidity?
Lateral rigidity refers to a structure's resistance to bending or flexing from side to side. In the context of vehicles, it is important for maintaining stability and handling during cornering. Components like sway bars and chassis bracing help improve lateral rigidity in vehicles.
Which shapes and designs are the strongest?
The triangle is the strongest geometric shape, but it's two-dimensional. Applying the idea (via cross bracing or the like) to construction is something that has been done for centuries. This is a simplified answer as the question is very general, but the application of a triangle or an angular tie to strengthen vertical elements and add rigidity to a structure is something that can be seen frequently.djsfjegythgeydgtryeg
Which state of matter posses maximum rigidity and why?
The solid state of matter possesses the maximum rigidity. In solids, particles are packed closely together in fixed positions, resulting in strong intermolecular forces that hold the particles in place. This fixed arrangement gives solids their definite shape and volume, thus providing rigidity.
Name the structure which provide rigidity in an animal cell?
The cytoskeleton is the structure that provides rigidity in an animal cell. It is made up of protein filaments such as actin, microtubules, and intermediate filaments, which help maintain cell shape and provide structural support.
what- Triangle rigidity means that a triangle cannot be deformed without changing its?
side lengths
Is the star the strongest shape?
No. On the lines to rigidity basis, a triangle is.
What is meant by the orthcentre of a triangle?
The 'orthcentre' of a triangle is at the point where the 3 perpendicular altitudes intersect within the triangle.
Can an isosceles triangle be similar to a right triangle?
If you meant right angle then yes
What is equelatiral triangle?
If equelatiral is meant to be equilateral, then it is a triangle whose three sides are of equal length.
What is meant by the sine of the triangle?
Nothing. Triangles don't have sines.
Does a salene have a right angle?
If you meant scalene triangle, then it may have a right angle. By definition, a scalene triangle is a triangle with no angle or side measures that are the same. For example, a 30,60,90 triangle is scalene.
Why does a triangle give greater rigidity to a structure than a rectangle?
A triangle provides greater rigidity to a structure than a rectangle due to its inherent geometric properties. In a triangle, the three sides create a stable shape that cannot easily deform without changing the length of its sides. In contrast, a rectangle can flex or distort under stress, as the angles can change while maintaining the lengths of the sides. This stability makes triangles ideal for supporting loads in construction and engineering applications.
What is the symbol the black triangle patches played during World War 2?
The black triangle meant the prisoner was antisocial.
How do you solve for x on a triangle?
That will depend what "x" is, and what other information you know about the triangle.
