Students can practice reading a protractor to measure angles in degrees with this educational worksheet.

I'll solve this angle measurement problem step by step.

Let me carefully read each protractor:

First Angle (top):
- The base line is at 0° on the right side
- The blue ray points to a number on the inner scale
- Looking at where the blue ray intersects the protractor, it's pointing at 70°

Second Angle (middle):
- The base line is at 0° on the right side
- The blue ray points to a number on the inner scale
- Looking at where the blue ray intersects the protractor, it's pointing at 50°

Third Angle (bottom):
- The base line is at 0° on the right side
- The blue ray points to a number on the inner scale
- Looking at where the blue ray intersects the protractor, it's pointing at 100°

Let me verify my readings:
- First angle: The ray goes from 0° to 70° ✓
- Second angle: The ray goes from 0° to 50° ✓
- Third angle: The ray goes from 0° to 100° ✓

Final Answer:
- Top angle: 70°
- Middle angle: 50°
- Bottom angle: 100°
