Answer:
convention" is "just the way a thing is done!" Unfortunately, sometimes conventions in math are glossed over, and you're expected somehow "to just know" what they are. If you, like me, missed some of the conventions that relate the geometry and trigonometry, please review the following.
In geometrical pictures (or "figures", in the parlance), points are customarily labelled with capital Latin letters such as A, B, and C. Straight lines, and especially segments, are often labelled with lower-case Latin letters, such as a, b, and c, but straight lines are sometimes also labelled as subscripted ells, such as L1 for "line one".
Corners of figures, such as the corners of squares, are called "vertices" (VURR-tuh-seez); the singular is "vertex" (VURR-teks).
If the meaning is clear, an angle may be referred to by just the point at its vertex, such as ∠C for the right angle show here:
Properly, angles should be named completely, such as ∠BCA.
