The vertex is b and the rays are ba and bc.
Acute: 0 < X < 90; Right: = 90; Obtuse: 90 < X < 180; Straight: = 180; Reflex: 180 < X < 360. The Acut, Right, Straight and Reflex are actually classifications of an angle. Naming of an angle is done by identifying the vertex and a combination of the vertex and points on the two rays. For example an angle with points ABC where B is the vertex and A and C are points on the accompanying rays may be named as angle B, angle ABC or angle CBA. These can be written with the symbol for angle placed before the B the ABC and the CBA.

Angle abc.
Oh honey, the vertex of an angle is just the fancy math term for the point where two rays meet to form that angle. It's like the corner of a room, but in math land. So next time you hear someone talking about a vertex, just remember it's where the angle's action is happening.

The vertex of the angle.

An angle can be defined as two rays or two line segments having a common end point. The endpoint becomes known as the vertex(shared endpoints). An angle occurs when two rays meet or unite at the same endpoint.An angle can be identified as ABC or CBA. You can also write this angle as B which names the vertex (common endpoint of the two rays)The vertex (in this case B) is always written as the middle letter. It matters not where you place the letter or number of your vertex, it is acceptable to place the it on the inside or the outside of your angle.You can also name the vertex by using a number. For instance, B could also be named angle 3 if you choose to change the letter to a number. Angle ABC or CBA would be names A3C or C3A or 3.
The VERTEX of the angle is always in the middle... so if it is angle ABC, then you can also name it CBA as long as the vertex letter is in the middle, usually there are only 2 ways to name an angle.Also, if there aren't any other angles with the same vertex, you can just call angle ABC, angle B.Summary: If you have an angle:the vertex is labeled B, the others are A and C. what can you call the angle?Answer: ABC,CBA or B
A central angle has its vertex at the center of a circle, and two radii form the Arms. Central angle AOC is described as subtended by the chords AC and by the arc AC. An inscribed angle has its vertex on the circle, and two chords form the arms. Inscribed angle ABC is also described as subtended by the chord AC and by the arc AC.
Angle abc will form a right angle if and only if, segment ab is perpendicular to segment bc.
there will be three vertex AB, BC, AC
For example, you might name an angle as "ABC", where "B" is the vertex, and "A" and "C" are points lying on the sides of the angle. If there are additional points on the same sides, you can substitute those points instead.
ABC angle is an angle,not a triangle!
