Taj Mahal- A brief introduction
The Taj is a white marble mausoleum located on the southern bank of
the Yamuna River in the Indian city of Agra. It was commissioned in
1632 by the Mughal emperor Shah Jahan (reigned 1628–1658) to house
the tomb of his favorite wife of three, Mumtaz Mahal.
Why we made this presentation?
We all know about Taj Mahal, many of us would have visited
it, but do you know that-
It is one of the best examples of line symmetry.
In both, exterior and interior, symmetry can be seen (and
even in the drainage system!!)
So we made this presentation to reiterate you with some of
the mathematical concepts in Taj Mahal.
This presentation won’t bore you but would take you through
the magical world of Maths!
Look closer and you’ll find a great example
of line symmetry – with two lines, one
vertical down the middle of the Taj, and
one along the waterline, showing the
reflection of the prayer towers in the
A variant is used in the great gate. In
the mausoleum the plan is expressed in
perfect cross-axial symmetry, so that
the building is focused on the central
tomb chamber. And the inner
organization is reflected on the
facades, which present a perfectly
balanced composition when seen from
the extensions of the axes which
generate the plan.
Bilateral symmetry dominated by a
central accent has generally been
recognized as an ordering principle of
the architecture of rulers aiming at
absolute power, as an expression of the
ruling force which brings about
balance and harmony, 'a striking
symbol of the stratification of
aristocratic society under centralized

Pointed arches within a rectangular frame also form the
iwans, or large recessed portals, that dominate the exterior
facades of the main buildings. Notably, the windows of all the
buildings imitate this design.

Phi (Φ) in Taj Mahal
Many of us won’t be knowing
what’s an Phi.
Phi is used as a symbol for
the golden ratio and on other
occasions in math and
science. This use is
separately encoded as the
Unicode glyph ϕ.
The Taj Mahal displays golden
proportions in the width of its grand
central arch to its width, and also in
the height of the windows inside
the arch to the height of the main
section below the domes.
