Why do many structures use triangles, according to the video?
For aesthetic purposes (looks good)
To reduce cost
To support, stabilise, and stiffen the structures
To make construction easier
Why are triangles used in structural engineering?
They are easy to calculate
They can support more weight without changing shape
They require fewer materials
They look better (aesthetically pleasing)
What shape did the initial structure fail with when a brick was placed on it?
Triangle
Rectangle
Circle
Parallelogram
In geometry, what name is given to a shape made of four triangles all stuck together?
Hexagon
Octagon
Tetrahedron
Pentagon
Why did the initial structure flatten when the brick was placed on it?
The materials were too weak
The parallelogram shape allowed it to flatten
The brick was too heavy
The base was too small
What are the three 'S's that triangles provide, according to the video?
Shape, Strength, Symmetry
Stability, Stiffness, Support
Size, Speed, Simplicity
Smoothness, Solidity, Sharpnes
What happened when the presenter stood on an aluminum can?
It supported his weight indefinitely
It crushed when tapped on the side
It immediately flattened
It bent slowly

Bridges
Window panes
Wall paint designs
What shape was the stool initially that made it unstable?
Triangle
Circle
Rectangle
Parallelogram
How did adding triangles affect the stool structure?
It made it more flexible
