In architecture, a triangular arch typically defines an arch where the intrados (inner surface of an arch) consists of two straight segments formed by two slabs leaning against each other.[1] Brick builders would call triangular any arch with straight inclined sides.[2] Mayan corbel arches are sometimes called triangular due to their shape.[3]
Since the sides of a triangular arch are experiencing bending stress, it is not a true arch in a structural sense. The design was common in Anglo-Saxon England until the late 11th century (St Mary Goslany).[1]
