To solve the problem of measuring and classifying each angle using a protractor, we need to follow these steps:
Step 1: Understand the Angle Types
-
Acute Angle: An angle that measures less than 90°.
-
Right Angle: An angle that measures exactly 90°.
-
Obtuse Angle: An angle that measures more than 90° but less than 180°.
-
Straight Angle: An angle that measures exactly 180°.
-
Reflex Angle: An angle that measures more than 180° but less than 360°.
Step 2: Measure Each Angle Using a Protractor
We will measure each angle and classify it based on its measurement.

Final Answers:
1. ☐ Acute
2. ☐ Obtuse
3. ☐ Reflex
4. ☐ Straight
5. ☐ Right
6. ☐ Obtuse
Boxed Final Answer:
\[
\boxed{
\begin{array}{ll}
1) & \text{Acute} \\
2) & \text{Obtuse} \\
3) & \text{Reflex} \\
4) & \text{Straight} \\
5) & \text{Right} \\
6) & \text{Obtuse} \\
\end{array}
}
\]
