Labelling angles and sides

Lines are often shown with letters at the points at either end.

We refer to the line using those two letters. For example, the line below would be called QR.

Often three letters are used to describe an angle.

Two lines, AB and AC meet at point A. AB joins the points A and B. AC joins the points A and C.

The angle between AB and AC is labelled BAC.

Angle BAC

The angle can written as BAC or BÂC or ∠BAC.

Question

What name would be given to this angle?

Diagram of angle LMN

This angle could be called LMN or NML.

The key thing is that the letter at the angle is the middle letter.
