In a triangle, what is generally the use of capital letters compared to lower case letters?

• They are used interchangeably.

• Capital letters are for the vertices (and the angle at the vertex); lower case letters are for the opposite side lengths.

• Lower case letters are for the vertices; upper case letters are for the opposite side lengths.
