Answer:
Alliteration, Repetition, Rhyme.
Explanation:
The given lines of poetry are taken from Rupert Brooke's poem "The Great Lover".
Alliteration- This is a technique when the same first letter of a given word is used again in the next word or close quarters. So, the alliteration in the given lines of poetry is "radiant raindrops/ couching.. cool/ sway.. sunny" etc. While radiant and raindrops start with "R", couching and cool starts with "C" and sway and sunny starts with "S". This is a pattern of alliteration.
Repetition is the use of the same word/ words in a consecutive pattern or a short space of the poem. This is used at times to emphasize the word. The repeated word in the given lines of poetry is "flowers"
Rhyme is the similarity in the sounds in the lines. This correspondence of such similar-sounding end words especially in lines of poetry is identified as the rhyme scheme. The rhyme in the given lines of poetry is in the words "flowers" and "hours" that have the same end-sound.
