This medium-level worksheet has students fill in blanks, and match items from two columns to practice angles and angle measurement skills.
It includes 10 questions across 2 sections for focused practice.
Style:
Angles and Measurement
Part A: Fill in the Blank
Write the missing word or number on each line.
1. When reading a protractor, always start counting from 0 degrees.
2. An angle slightly larger than a right angle, say 95°, is classified as obtuse.
3. If a protractor shows 130° on the outer scale, the inner scale reads 50 degrees.
4. The hands of a clock at 9:00 form a right angle measuring 90°.
5. An angle that measures exactly 0° means the two rays overlap.
6. The supplement of a 45° angle is 135 degrees.
7. An angle of 91° is obtuse because it is just over 90°.
8. The complement of a 60° angle is 30 degrees.
9. A clock hand moving from 12 to 3 sweeps 90 degrees.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Clock at 12:00
→ 0°
30°
Clock at 3:00
→ 90°
90°
Clock at 6:00
→ 180°
180°
Clock at 1:00
→ 30°
