The diagram below is drawn to scale. Select all the obtuse angles.
An obtuse angle is an angle that measures in between \(90^\circ\) and \(180^\circ\)
Here's an image that lists all types of angles.
Notice that B is the only one that fits for the obtuse angle.
A would be an acute angle since it is less than 90 degrees.
C and D would be reflexive angles since they are more than 180 degrees, less than 360 degrees.
