Final Answer — which in this case means listing the measured angles for all problems shown.
However, since I cannot physically measure angles from an image (I don’t have a protractor or interactive tools), I must estimate based on standard geometric conventions and typical worksheet designs. These worksheets usually use clean, round numbers (like 30°, 45°, 60°, 90°, 120°, 135°, 150°, etc.) for clarity.
Let’s go section by section and estimate each angle visually:
---
Section A:
1) Acute angle — looks like ~30°
2) Obtuse angle — looks like ~135°
3) Acute angle — steeper than #1, maybe ~70°
4) Very small acute angle — ~15°
5) Obtuse angle — almost straight, maybe ~160°
6) Reflex angle? Wait — the arc shows the *inside* angle, which is obtuse — looks like ~120°
7) Full circle with a small gap — that’s a reflex angle? Actually, the arc goes around the outside — so it’s 360° minus a small angle. The small angle looks ~20°, so reflex = 340°
Wait — let’s recheck #7: The arc is drawn going the long way around — yes, that’s a reflex angle. If the small opening is about 20°, then the marked angle is 360° - 20° = 340°.
But actually, looking again — the arc is drawn *around* the vertex, covering most of the circle — yes, 340° is reasonable.

Section B:
1) Small acute angle — ~20°
2) Very small acute angle — ~10°
3) Obtuse angle — ~135°
4) Reflex angle — the arc goes the long way. The small angle inside looks ~60°, so reflex = 300°
5) Obtuse angle — ~120°
6) Reflex angle — the arc covers more than 180°. The inner angle looks ~135°, so reflex = 360° - 135° = 225°? Wait — no, the arc is drawn on the *outside*, meaning it's measuring the larger angle. Looking at the shape, the two lines form an angle that opens to the right — the arc goes over the top, so it’s measuring the reflex angle. The actual inner angle looks ~135°, so reflex = 360° - 135° = 225°. But wait — maybe it’s drawn as 225° directly? Let’s say 225°.
Actually, let’s look again: In #6 Section B, the two lines form an angle that looks like 135° if you take the smaller one, but the arc is drawn on the *larger* side — so yes, 360° - 135° = 225°.
7) Almost straight line — slightly bent downward. Looks like ~170° (since straight is 180°, this is just under).

Now, let’s compile estimates:
Section A:
1) 30°
2) 135°
3) 70°
4) 15°
5) 160°
6) 120°
7) 340°
Section B:
1) 20°
2) 10°
3) 135°
4) 300°
5) 120°
6) 225°
7) 170°
These are reasonable estimates based on typical worksheet design and visual approximation.
Final Answer:
Section A: 1) 30°, 2) 135°, 3) 70°, 4) 15°, 5) 160°, 6) 120°, 7) 340°
Section B: 1) 20°, 2) 10°, 3) 135°, 4) 300°, 5) 120°, 6) 225°, 7) 170°
