Problem: Classify the following angles according to their type.
To solve this problem, we need to classify each angle based on its measure. Angles are typically classified into the following 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°.
Now, let's analyze each angle in the image and classify it accordingly.

Final Answer:
\[
\boxed{
\begin{array}{ccc}
1) & \text{Acute Angle} & 2) & \text{Straight Angle} & 3) & \text{Obtuse Angle} \\
4) & \text{Reflex Angle} & 5) & \text{Right Angle} & 6) & \text{Acute Angle} \\
7) & \text{Obtuse Angle} & 8) & \text{Acute Angle} & 9) & \text{Reflex Angle} \\
10) & \text{Straight Angle} & 11) & \text{Obtuse Angle} & 12) & \text{Right Angle}
\end{array}
}
