Within the Angels & Demons story-world, yes: the single page Langdon and Vittoria tear out and study is treated as the page that contains all the key clues—the hidden poem and the hints about the four altars and the Path of Illumination.
However, a couple of important nuances:
What the movie/book actually show
The film has Langdon discover Galileo’s banned manuscript, Diagramma della Verità / Veritatis, in the Vatican Archives, then Vittoria tears out one page. That page is where Langdon spots the odd, poetic passage about the path of light and the four elements.
The book describes Diagramma as Galileo’s most secretive work, containing a coded poem that outlines the Path of Illumination and points to altars of earth, air, fire, and water in Rome.
Fan analyses and prop replicas identify that torn page as “the page with the poem”—the one that gives the sequence of clues (“earth,” then “air,” then “fire,” then “water”) and the instruction to let angels guide the seeker.
So in the narrative, “page 5” (or the specific page they tear out) is the page that matters for the plot: it has the poem and associated markings that launch the whole path.
POTUS called the earth terra because in latin is the word for the earth, dirt, one of the four elements, so we are terrans

Within the logic of the Angels & Demons movie, yes: the page they’re after is effectively “D5”—Galileo’s third “D‑text,” with its key secret hidden specifically on page 5
The path is marked by the four elements.
It hints that the path runs through four altars, each associated with a classical element:
Earth
Air
Fire
Water
These are not abstract ideas; they correspond to specific physical locations in Rome.
