What pasta shape is a short tube cut diagonally?

The pasta shape that is a short tube cut diagonally is penne.

Penne are extruded pasta tubes with ends sliced at an angle, giving them their distinctive pointed appearance. The diagonal cut helps sauce cling to the pasta and allows ingredients such as vegetables, meat, or cheese to collect inside the hollow center. Penne are usually made from durum wheat flour and water.

The name comes from the Italian word penna, meaning feather or quill, and is related to the English word “pen.” The shape was designed to resemble the metal nibs used in fountain and dip pens. Unlike many pasta shapes, penne has a documented origin: in 1865, Genoese pasta maker Giovanni Battista Capurro patented a machine for cutting pasta diagonally.

Penne rigate has ridges on its surface, while penne lisce is smooth. Penne is often confused with ziti, another tubular pasta, but ziti generally has straight-cut ends and is longer.
