Curriculum Australian Curriculum V9 Australian Curriculum V8 WebThe vertex of an angle is the common endpoint of two rays that make up the angle's sides. The vertex for angle BAC, written ∠BAC, is point A. The angle can also be named as ∠CAB or by only its vertex, ∠A. When using three points to name the angle, always put the name of the vertex in the middle. So, ∠BAC is not the same angle as ∠ABC or ∠BCA. how to use red pepper
