Let's solve the "Classifying Angles" worksheet step by step.

🔹 Understanding the Types of Angles:

1. Straight angle: Exactly 180° — looks like a straight line.
2. Right angle: Exactly 90° — forms a perfect "L" shape (like the corner of a square).
3. Acute angle: Less than 90° — smaller than a right angle.
4. Obtuse angle: Greater than 90° but less than 180° — wider than a right angle but not a straight line.

Now, let’s analyze each of the 9 angles in the grid:

✔ Step-by-Step Classification:

#### Row 1:
1. First angle – Looks like a perfect "L" shape → Right
2. Second angle – Looks like a bent line, more than 90° → Obtuse
3. Third angle – A long thin line with a small bend → Acute

#### Row 2:
4. Fourth angle – Looks like a sharp "V" shape, less than 90° → Acute
5. Fifth angle – Perfect "L" shape again → Right
6. Sixth angle – A sharp V-shape, very narrow → Acute

#### Row 3:
7. Seventh angle – Looks like a wide open angle, more than 90° → Obtuse
8. Eighth angle – Looks like a long straight line with a tiny bend → Straight
9. Ninth angle – Looks like a bent corner, more than 90° → Obtuse
