Work Step by Step
To distinguish between the symbols F, E, L, and T using geometric properties, we can focus on a few key structural features that are visually and spatially distinct:
Key Geometric Properties
Property F E L T
Number of horizontal bars 2 3 1 1
Vertical stem Yes Yes Yes Yes
Symmetry No Yes (vertical) No Yes (vertical)
Top bar alignment Left Full width Left Centered
Bottom bar alignment Left Full width Left None
Middle bar Present Present None None
Explanation of Properties
Horizontal bars:
F has two (top and middle),
E has three (top, middle, bottom),
L has one (bottom),
T has one (top).
Symmetry:
E and T are vertically symmetrical.
F and L are asymmetrical.
Bar alignment:
F and L have left-aligned bars.
E spans full width.
T has a centered top bar.
Minimal Distinguishing Set
To uniquely identify each symbol, you only need:
Number of horizontal bars
Presence and position of middle bar
Symmetry (vertical)
These three properties are sufficient to distinguish F, E, L, and T in most geometric or typographic contexts.
