Explanation:
Your question pertains to types of arches typically found in architecture. The term you're likely looking for in regard the term for a 'false' or pseudo-triangular arch is known as a Gothic Arch. This is also sometimes known as a pointed arch, and was a fundamental element of the Gothic style of architecture, possibly influenced by Islamic architecture.
The Gothic Arch differs from 'true' arches, such as the Keystone Arch in that it is pointed, rather than rounded. In a Keystone Arch, the 'keystone' is the voussoir (wedge-shaped block) at the top of the arch that holds all other voussoirs in place. This forms a 'true' rounded arch with a keystone in the center to provide structural integrity.
Other types of arches mentioned in your question, the Ogee Arch and the Segmental Arch, are variations on arch structures, but the Gothic Arch is the 'triangular' or pointed arch most often perceived as 'false' due to its contrast with the traditional rounded arch form.
