In a number of hiragana the first two strokes form the appearance of a "V" with varying acute angles:
from narrow, almost parallel lines to a large obtuse angle; to say nothing of the degree of rounding in the the angle.
To the right, one may find different strokes signifying an entirely different syllable.
To confuse matters, there are always a number of hiragana that are somewhat similar in outline.
I will try to differentiate between them and provide examples.

KE
