Arc ogival (pointed arch)

The pointed arch has three shapes (see picture from Wikipedia):

1. lancet arch (arc brisé en lancette)
2. equilateral pointed arch (arc brisé en tiers-point)
3. lowered pointed arch

In case of a lancet arch the centre of one arc lies outside the opposite arc. The equilateral pointed arch is an arc (arch) based on an equilateral triangle; the centres of the arcs with radii R1 and R2 are M1 and M2.
The picture shows a row of pointed arcs (arches) in the nef (nave) of the Saint-Pierre in Brancion (Martailly-lès-Brancion).
See also arc brisé (synonym), lancette, tiers-point, ogive, voûte d'ogives and croisée d'ogives.
