To find out what these letters have in common, we need to look for any unique properties or characteristics that distinguish them from the rest of the English alphabet. One approach is to examine the letters individually and compare them to the others.
Upon closer inspection, we can observe that each of these letters lacks any vertical lines in their uppercase form. Let's break it down:
B: Contains two curved lines
D: Contains one curved line
E: Contains three horizontal lines
F: Contains two horizontal lines
H: Contains two vertical lines
K: Contains two diagonal lines
L: Contains one diagonal line
M: Contains three diagonal lines
N: Contains two diagonal lines
P: Contains one curved line
R: Contains two diagonal lines
In contrast, the other letters in the English alphabet consist of at least one vertical line in their uppercase form, such as A, C, G, I, J, O, Q, S, T, U, V, W, X, Y, and Z.
Therefore, the common property shared by the letters B, D, E, F, H, K, L, M, N, P, and R is that they all lack any vertical lines in their uppercase forms.
