how many angle, vertex and arms does a obtuse angle have?

Dear student ,

A

                O                           B

You can see there is 

One Vertex  = " O "

One Angle = " AOB "

Two Arms = " A " & " B "

Hope it helped .

Angle depennds as an obtuse angle can have many angles but it has one vertex and two arms same in every angle.
Thank you
