[Intro]

Dihedral triangular
(Can your mind’s eye see…)
In 3D
[Bridge]
(da, dee, dee)
Up the bid
(Build a pyramid)

[Verse 1]

Will your base
Take a side
The human race
Shall decide

[Bridge]

Dihedral triangular
(Can your mind’s eye see…)
In 3D (da, dee, dee)

[Chorus]

Castles of your dreams
(Make things what they seem)
Turning dreams to scenes
(Sower of seeds and seams)

[Bridge]

Build a pyramid
(We did!)
(Pyramid)

[Verse 2]

All sides hold us together
Proud to report (group support)
Hope resides in whether
We resort (in our last hope)

[Bridge]

Dihedral triangular
(Can your mind’s eye see…)
In 3D (dee, dee)

[Chorus]

Castles of your dreams
(Make things what they seem)
Turning dreams to scenes
(Sower of seeds and seams)

[Outro]

Turning dreams to scenes
(Turning dreams to scenes seen)

A MATH AND SCIENCE NOTE

Pyramid (like a square-based pyramid):

  • Think of a 3D shape with a base (usually a square) and triangular sides that meet at a single top point (the apex).

  • The faces (the sides) are usually isosceles triangles.

  • Angles in a pyramid:

    • The base angles of the triangular sides are typically equal (like an isosceles triangle).

    • The angles between the base and sides (called dihedral angles) are important in 3D — they control how steep or flat the pyramid is.

    • The triangles themselves have angles depending on the slope of the pyramid.

      So pyramids are made up of isosceles triangles, and their structure involves a mix of plane angles (in the triangles) and 3D angles (between faces).
