Well, after studying extensively on this subject for countless years at the University of Cambridge, my colleagues and I have determined that, in fact, an arch is BY FAR the stronger of the two shapes. It is a common misconception that a triangle is stronger, and it has been my life work to prove this fact wrong. That is all.
-Yea, after reading this I have to agree 100%. I remember working on a science project in the fifth grade and this tool bag argued with me over this point by saying that triangles were stronger. We went with his idea, which led us to FAIL our PROJECT.
-This sounds right and I would agree. However, I must add that, a GROUP of triangles together can be potentially stronger than an arch. A single triangle is far weaker than an arch.
An arc.
Circles are a stronger geometrical shape than a triangle. Circles distribute weight equally which makes it more stable. That is why pot holes are circles.
A triangle must have straight lines.
what shape is not a triangle but has 3 sides
A triangle is a geometric shape.
A circles structural shape is in fact stronger than a triangles structural geometric shape.
An arc.
triangle for small parts and an arch for a large part.

Type your answer here... arch
Given unchanging lengths of the sides, a triangle cannot change its shape. But given unchanging lengths of the sides of a rectangle, it can change its shape by some force by changing its angle measurements. If a 2d load were put on a rectangle, enough force could squish the rectangle into a parallelogram, whereas a triangle cannot change shape without changing the lengths of its sides or bending its sides out of shape (most likely into a curve).Given these properties, a rectangle can collapse its shape much more easily and is flimsy compared to a triangle.
The bridge is supported by an arch or a series on arches to make the bridge stronger.
a truss
what shape is not a triangle but has 3 sides
A triangle is a geometric shape.
simple arch shape, like dc has round domes, cirlcles. simple shape, really.
