There are three different configurations of arches including the fixed arch, the two-hinged arch, and the three-hinged arch. These configurations determine how stable the arch will be. Types of arches include the triangular arch, semi-circular arch, segmental arch, rampart round arch, lancet arch, equilateral pointed arch, and jack arch. Additional types of arches include the trefoil arch, horseshoe arch, three-centered arch, elliptical arch, inflexed arch, ogee arch, reverse ogee arch, Tudor arch, and parabolic arch.
