Printable math worksheet for students to practice measuring angles, divided into two sections with various angle types.

Since the user has set all options (ExplainAnswer, TeachTopic, GeneratePractice) to false, and the task is to solve the problem accurately without describing the image or mentioning its source, I will proceed to measure each angle as if I were using a protractor on the printed worksheet.

However, since I cannot physically place a protractor on the image, I will estimate the angles based on visual comparison with standard reference angles (0°, 45°, 90°, 135°, 180°, 270°, 360°), and provide reasonable approximations that would be expected in a classroom setting for such worksheets.

Let’s go step by step for each angle:

---

Section A

1) This is an acute angle — looks like about 30°.
2) Obtuse angle — wider than 90°, maybe around 120°.
3) Acute but steeper — close to 70°.
4) Very small acute angle — approximately 15°.
5) Obtuse — almost straight, maybe 160°.
6) Reflex angle? Wait — the arc shows the smaller angle inside, which is obtuse — about 135°.
7) Full circle minus a small wedge — reflex angle? The arc goes around the outside — so it's 360° minus a small angle (~15°) → 345°.

Wait — let me recheck #7: The arc is drawn around the larger side, meaning it’s measuring the reflex angle. Since the small angle between the lines looks like ~15°, the reflex angle is 360° - 15° = 345°.

Section B

1) Small acute angle — similar to Section A #4 — about 20°.
2) Even smaller — maybe 10°.
3) Obtuse — looks like 135°.
4) Reflex angle again — the arc is on the big side. The small angle looks like ~60°, so reflex = 360° - 60° = 300°.
5) Acute? No — actually, the arc is on the inside, and it’s clearly obtuse — about 120°.
6) Reflex? Arc is on the inside — it’s an obtuse angle — about 135°.
7) Almost straight — slightly less than 180° — maybe 170°.

Wait — let me double-check Section B #6: The two lines form an angle that opens downward, and the arc is drawn on the inside — it’s definitely obtuse, not reflex. So ~135° is correct.

Section B #7: The angle is almost flat — just a little bent — so 170° makes sense.

Now, compiling all estimates:

Section A:
1) 30°
2) 120°
3) 70°
4) 15°
5) 160°
6) 135°
7) 345°

Section B:
1) 20°
2) 10°
3) 135°
4) 300°
5) 120°
6) 135°
7) 170°

These are reasonable estimates for a student using a protractor on this worksheet. In real classroom use, students might get slightly different values depending on how precisely they align the protractor, but these are within typical acceptable ranges.

Final Answer:
Section A: 1) 30° 2) 120° 3) 70° 4) 15° 5) 160° 6) 135° 7) 345°
Section B: 1) 20° 2) 10° 3) 135° 4) 300° 5) 120° 6) 135° 7) 170°
