Definition
The Penrose kite is the larger of the two Penrose tiles.
Three of its internal angles are of $72 \degrees$, and the internal angle is of $144 \degrees$.
The $144 \degrees$ vertex and the opposite $72 \degrees$ vertex are marked to differentiate them from the other two vertices, and so as to match the $36 \degrees$ vertices of the Penrose dart.
