Pythagoras Goes Complex — Imaginary Right Triangle T-Shirt (Soft Fitted)

$20.40
A perfectly ordinary right triangle. Legs of length 1 and i (the imaginary unit). Hypotenuse, by Pythagoras: sqrt(1^2 + i^2) = sqrt(1 + (-1)) = 0. So this is a triangle with a hypotenuse of length zero. Which is also an extremely degenerate triangle. Which is also fine, because we never said it was real. For mathematicians, complex-analysis survivors, anyone who has lectured undergraduates that "yes, geometry breaks when you go complex, that's the whole point", and anyone who appreciates how much chaos a tiny i can cause. Minimal line art — three lines, a right-angle marker, three italic labels. No words. The diagram is the punchline. Printed on a Bella+Canvas Supersoft tee: lightweight, exceptionally soft, with a smooth print surface. Closer, more fitted unisex cut. Dark-shirt version — white artwork, shown on darker garment colours.

Our suppliers provide the measurements. There might be a variation of up to 2 inches (5 cm) in the product measurements.

A useful tip is to compare these measurements with those of a product you have at home.

A Length

Begin at the collar's edge at the top of the t-shirt (the highest shoulder point) and extend the tape to the shirt's bottom.

B Width

Start the tape at the seam just below one sleeve and stretch it across to the seam below the other sleeve.
