how do you name a obtuse angle

Question

when you are naming an angle just look for where the angle occurs and when writting it place it in the middle of the three points and draw a little triangle thingy over the top for eg. angle ABC would mean the angle occurs at B

If it is bigger than a 90 degress.(Is bigger than a right angle) Which means it is exactly perfect in the corner. Like an L. The corner i s a right angle. So if it was bigger than that it would be an obtuse angle.
