A triangle on a gravestone usually stands for the Holy Trinity; the three-lobed trefoil and interlaced triquetra carry the same meaning.
Christians used the equilateral triangle for the Father, Son and Holy Spirit. Other three-part shapes do the same: the trefoil, like a three-leaf clover, and the triquetra, three interlaced loops.
An eye inside a triangle is the all-seeing eye of God and has its own entry. An inverted triangle with letters may instead be the Knights of Pythias emblem, so check for F, C and B.
