Answer:
1. five feet - pentameter
2. one foot - monometer
3. two feet - dimeter
4. seven feet - heptameter
5. four feet - tetrameter
6. three feet - trimeter
7. six feet - hexameter
8. eight feet - octameter
Explanation:
This question refers to meter in poetry, which is done by counting the number of syllables. However, different types of meter will count syllables in different ways. An iambic pentameter, for example, will consider an unstressed syllable plus a stressed one as one foot. Each line will repeat that pattern five times, which is why it is called pentameter.
To match the columns above, we need to know the meaning of the different prefixes used:
mono - one
di - two
tri - three
tetra - four
penta - five
hexa - six
hepta - seven
octa - eight
Remember that those same prefixes are used in other fields of knowledge? For instance, in geometry, a pentagon is a figure with five sides and five angles.
