how do you name a obtuse angle
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.
To name an angle, you typically use three points: one point for the vertex (the middle point), and two additional points that lie on each of the two rays that form the angle. The vertex is placed in the middle of the three points, and you can draw a small arc or use a symbol to represent the angle.
To name an obtuse angle specifically, you follow the same process. If the angle is larger than a right angle (90 degrees) but less than a straight angle (180 degrees), it is an obtuse angle. When naming it, you use the three points as usual, with the vertex in the middle, and indicate that it is an obtuse angle by adding a small arc or an "obtuse angle" symbol over the angle name.
For example, if you have an angle with vertex P, and the rays extend from points Q and R, and it is an obtuse angle, you could name it as "angle PQR" or "angle RQP". In either case, you would add a small arc or an "obtuse angle" symbol above the angle name to indicate that it is an obtuse angle.
