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