The Iamb is a poetic foot, not a meter. You need to know how many iambs in a line in order to call it a meter. Iambic pentameter is a meter; there are 5 (penta) iambs per line. An iambic foot is two syllables that have the stress pattern: begin revoke shazam
I want to say 2, once at each corner
2
Just the two of them at each end of the line segment.
A line has infinitely many subsets, not just three. Any collection of points on the line constitute a subset.

70 metric feet? well, a sonnet is a short poem consists of fourteen lines. Each line is usually written in iambic pentameter (five iambs... an iamb is equivalent to one metric foot). Meaning, 14 lines of 5 iambs each is equal to 70 iambs or metric feet.
A verse typically contains a specific number of iambs, which are pairs of syllables with one stressed (accented) and one unstressed (unaccented). In a line of iambic pentameter, for example, there are 10 iambs (5 pairs) per line. The number of iambs in a verse will depend on the specific meter and structure of the poem.
At fourteen lines and five iambs per line, a little grade school arithmetic gives us 70 iambs altogether in the poem.

The rhythm of a poem depends on what metre is used to write it. The units of metre can be iambs, trochees, anapaests, or a number of others and there may be different ones and different numbers of these in each line. Iambic pentameter, for example contains five (penta-) iambs in each line. In such a poem, the units of meter are iambs. Trochaic hexameter would give you six (hexa-) trochees in each line. However, poems are frequently unable to be 'measured' in such simplistic terms.
Shakespeare's verse is in iambic pentameter, with five iambs to the line.
"tetrameter" - it has 4 "iambs"
The meter of "Night approaches bringing shadows" is in iambic pentameter, consisting of five iambs in each line (unstressed syllable followed by a stressed syllable).
iambic tetrameter (unstressed syllable followed by stressed syllable with four feet per line) the only lines that are different are ones that just say "in flanders fields" these are iambic dimeter
There are five iambic feet in a line from Sonnet 18 which consists of ten syllables alternating in stress pattern, such as: "Shall I compare thee to a summer's day?"
It all depends on the length of the prologue and the regularity of the metre. The prologue to Romeo and Juliet is fourteen lines long, and each line contains approximately five iambs, making a total of seventy in the whole prologue. That's more or less, since lines like "From ancient grudge break to new mutiny", it can be argued, contain only four iambs and one trochee. Romeo and Juliet is not the only one of Shakespeare's plays which has a prologue, however. Henry V has a particularly famous one which is 34 lines long, which would contain one hundred and seventy iambs if it were regular. (It isn't though. The first line "O for a muse of fire that would ascend" contains only 4 iambs and starts with a trochee) The Prologue to Henry IV Part II has 40 lines (200 iambs more or less) and the Prologue to Pericles has 42 lines of iambic tetrameter with 4 iambs to the regular line, a total of 168, more or less.
