Naming Angles There are several ways to name this angle. 1) Use the vertex and a point from each side. S SRT or TRS side The vertex letter is always in the middle. 2) Use the vertex only. 1 R T side vertex R If there is only one angle at a vertex, then the angle can be named with that vertex. 3) Use a number. 1
