Triangular arch
In architecture, a triangular arch (sometimes angular arch[1]) typically defines an arch where the intrados (inner surface of an arch) consists of two straight segments formed by two stone slabs leaning against each other.[2][3] In this roof-like[4] arrangement, mitre joint is usually used at the crown, thus the arch was in the past also called a mitre arch.[5] Brick builders would call triangular any arch with straight inclined sides.[6] Mayan corbel arches are also sometimes called triangular due to their shape.[7]
Since the sides of a triangular arch are experiencing bending stress, it is a false arch[3] in a structural sense (historically preceding the invention of true arches[8] and going back to Neolithic times[9]). The design was used in Anglo-Saxon England until the late 11th century (St Mary Goslany) over small openings.[2][1]
