Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Identify the type of angle.
2	Step	The given image shows the obtuse angle.
3	Step	An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.
4	Step	Compare the given options with the definition of a obtuse angle.
5	Step	So the given image is a obtuse angle.
