Looking at question 4, I can see an angle that is clearly less than 90 degrees. The two rays form a narrow opening, similar to question 1. This is characteristic of an acute angle.
Now I'll summarize my findings for all four questions:
1. Question 1: Acute Angle (less than 90 degrees)
2. Question 2: Right Angle (exactly 90 degrees)
3. Question 3: Obtuse Angle (greater than 90 degrees but less than 180 degrees)
4. Question 4: Acute Angle (less than 90 degrees)
This completes the identification of all angles in the worksheet.
