Summary:
A complete protein is a protein source that "contains adequate proportions of the nine essential amino acids" that our body can not produce on its own.
Relatively low in protein, a single cup of strawberries contains 1 grams of protein, or about 2% of recommended daily values. [1]
To get the adequate amount of protein with strawberries alone, you will need 49 cups of strawberries (7460 grams) for an average female, or 59 cups of strawberries for males. [4] That's over 2390 calories, and a lot of strawberry! Pairing strawberry with a richer protein source is a good idea.

Proportionally, strawberry does contain abundant amounts of 3 out of the nine essential amino acids. However, strawberry is a little short on isoleucine, leucine, lysine, methionine, phenylalanine and valine.[1]
To have adequate amounts of all nine essential amino acids with strawberry alone, you will have to eat 283 cups of strawberries (43000 grams) for an average person. [2]
That's about 476% more strawberry to compensate for the lack of isoleucine, leucine, lysine, methionine, phenylalanine and valine, compared to the protein requirement alone.
