Problem: Identify the type of angle for each image.
To solve this problem, we need to classify each angle based on its measure. Here are the definitions of the different types of angles:
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 Rotation (or Complete Angle): An angle that measures exactly 360°.
Now, let's analyze each angle in the image:
---
####
Row 1:
1. The angle is a straight line, so it measures 180°.
-
Type: Straight Angle
2. The angle measures 29°.
-
Type: Acute Angle
3. The angle has a square symbol, indicating it measures 90°.
-
Type: Right Angle
---
####
Row 2:
4. The angle measures 10°.
-
Type: Acute Angle
5. The angle measures 171°.
-
Type: Obtuse Angle
6. The angle is larger than 180° but less than 360°.
-
Type: Reflex Angle
---
####
Row 3:
7. The angle measures 91°.
-
Type: Obtuse Angle
8. The angle forms a full circle, so it measures 360°.
-
Type: Full Rotation (Complete Angle)
9. The angle measures 85°.
-
Type: Acute Angle
---
####
Row 4:
10. The angle measures 180°.
-
Type: Straight Angle
11. The angle measures 108°.
-
Type: Obtuse Angle
12. The angle has a square symbol, indicating it measures 90°.
-
Type: Right Angle
---
####
Row 5:
13. The angle measures 239°.
-
Type: Reflex Angle
14. The angle forms a full circle, so it measures 360°.
-
Type: Full Rotation (Complete Angle)
15. The angle has a square symbol, indicating it measures 90°.
-
Type: Right Angle
---
Final Answer:
\[
\boxed{
\begin{array}{ccc}
\text{1. Straight Angle} & \text{2. Acute Angle} & \text{3. Right Angle} \\
\text{4. Acute Angle} & \text{5. Obtuse Angle} & \text{6. Reflex Angle} \\
\text{7. Obtuse Angle} & \text{8. Full Rotation} & \text{9. Acute Angle} \\
\text{10. Straight Angle} & \text{11. Obtuse Angle} & \text{12. Right Angle} \\
\text{13. Reflex Angle} & \text{14. Full Rotation} & \text{15. Right Angle} \\
\end{array}
}
