Problem: Identify the type of angle for each image.
#### Angle Types:
1.
Acute Angle: An angle that measures less than 90°.
2.
Right Angle: An angle that measures exactly 90°.
3.
Obtuse Angle: An angle that measures more than 90° but less than 180°.
4.
Straight Angle: An angle that measures exactly 180°.
5.
Reflex Angle: An angle that measures more than 180° but less than 360°.
6.
Full Angle (or Complete Angle): An angle that measures exactly 360°.
#### Solution:
Let's analyze each image step by step:
1.
Image 1: The angle appears to be a straight line.
-
Type: Straight Angle (180°).
2.
Image 2: The angle is labeled as 29°.
-
Type: Acute Angle (less than 90°).
3.
Image 3: The angle forms a square corner.
-
Type: Right Angle (90°).
4.
Image 4: The angle is labeled as 10°.
-
Type: Acute Angle (less than 90°).
5.
Image 5: The angle is labeled as 171°.
-
Type: Obtuse Angle (more than 90° but less than 180°).
6.
Image 6: The angle appears to be more than 180° but less than 360°.
-
Type: Reflex Angle (more than 180° but less than 360°).
7.
Image 7: The angle is labeled as 91°.
-
Type: Obtuse Angle (more than 90° but less than 180°).
8.
Image 8: The angle forms a complete circle.
-
Type: Full Angle (360°).
9.
Image 9: The angle is labeled as 85°.
-
Type: Acute Angle (less than 90°).
10.
Image 10: The angle is labeled as 180°.
-
Type: Straight Angle (180°).
11.
Image 11: The angle is labeled as 108°.
-
Type: Obtuse Angle (more than 90° but less than 180°).
12.
Image 12: The angle forms a vertical line.
-
Type: Straight Angle (180°).
13.
Image 13: The angle is labeled as 239°.
-
Type: Reflex Angle (more than 180° but less than 360°).
14.
Image 14: The angle forms a complete circle.
-
Type: Full Angle (360°).
15.
Image 15: The angle forms a horizontal line.
-
Type: Straight Angle (180°).
#### Final Answer:
\[
\boxed{
\begin{array}{ccc}
1. \text{Straight Angle} & 2. \text{Acute Angle} & 3. \text{Right Angle} \\
4. \text{Acute Angle} & 5. \text{Obtuse Angle} & 6. \text{Reflex Angle} \\
7. \text{Obtuse Angle} & 8. \text{Full Angle} & 9. \text{Acute Angle} \\
10. \text{Straight Angle} & 11. \text{Obtuse Angle} & 12. \text{Straight Angle} \\
13. \text{Reflex Angle} & 14. \text{Full Angle} & 15. \text{Straight Angle} \\
\end{array}
}
\]
