The letter that has no angles is the letter "O".

To determine which letter has no angles, you need to identify the letters that consist solely of straight lines without any angles. Here's a step-by-step breakdown to find the letter:

1. Analyze each letter of the English alphabet, considering both uppercase and lowercase forms.
2. Start with the simplest letters that consist solely of straight lines without any angles, such as I and l.
3. Evaluate other letters that may contain angles, such as A, M, or V.
4. Continue the process until you find the letter that matches the criteria.

After following these steps, you will come across the letter O, which has no angles. O is a circular shape without any straight lines.
