I have a spreadsheet where there is one table with the headings:

Coordinate, Lat, Long

Another with headings

Triangle, Coordinate 1, Coordinate 2, Coordinate 3, Area

What this is for, is taking the triangles formed by the specified three coordinates' area based off of Girard's theorem, as they are all spherical triangles. I need to take the specific latitude and longitude values from the first table based on the coordinate numbers underneath the three coordinate headings in the second table. I hope this makes sense. Here are pictures detailing what the two tables look like:

Table 1

Table 2

Thanks in advance. And I really do hope this makes sense.
