Now, with that out of the way, let's just start from the basics, a basic starting point from geometry, and then we can just grow from there. The angle can written as BAC or BC or BAC. And the way that we would Label an angle using numbers Label an angle using the vertex and a point from each arm ABC or CBA Note: The vertex should go between the two points. A and I wanna go to D, but I want the option of keep Angles | Geometry (all content) | Math | Khan Academy So we can go back or all in any direction while staying on that point, that means you have zero thing as angle APC. had a line between AC.
