This adjustment reflects that the arch is self-supporting, but temporary supports from the under, normally in the form of timber centers (occasionally called centering or arch formers), must be provided until the keystone has been established in place. Intrados of this arch is lesser than a semicircle. The Venetian arch is another form of the pointed arch. [10], The two-hinged arch is most often used to bridge long spans. Wedge-shaped blocks, named voussoirs, establish flank-to-flank with the upper perimeter being broader than the lower edge.

A flat arch is built by jointly supporting wedge shaped masonry units known as voussoirs. Construction of the arches is needed where the span between the two supports is surplus and the load arriving on the supports is heavy. The external thrust put out by an arch at its floor must be restricted either by the weight of supporting walls or weight, by foundations, or by a contradicting tie between the two sides.
