Intro to Geometry and Identifying Angles
... Point A is the vertex of angle BAC. Line AB and Line AC meet at Point A. Lines are identified by two points, as in Line AB. Angles are identified by three points with the middle point always being the vertex as in Angle BAC. An angle is measured in terms of a unit knows as a “degree” (o). There are ...
