📐 Part 1: Identifying and Naming Angles

a) An angle that measures exactly 90°:

b) An angle that measures 45°:

c) An angle that measures 120°:

📏 Part 2: Measuring and Comparing Angles

a) Angle A measures: _________ degrees

b) Angle B measures: _________ degrees

c) Which angle is larger? _________

a) In a triangle, if two angles measure 60° and 70°, the third angle measures: _________

b) In a rectangle, each corner angle measures: _________

c) The angles around a point add up to: _________

a) A reflex angle is always greater than a straight angle. TRUE / FALSE

b) Two right angles make a straight angle. TRUE / FALSE

c) An obtuse angle is smaller than a right angle. TRUE / FALSE

🔧 Part 3: Problem Solving

📋 Answer Key

1. a) Right angle, b) Acute angle, c) Obtuse angle

2. 200° and 270° (reflex angles)

3. Check drawings show: acute (<90°), right (90°), obtuse (90°-180°), reflex (>180°)

4. Answers will vary based on provided angles

5. a) 50°, b) 90°, c) 360°

6. a) TRUE, b) TRUE, c) FALSE

7. Right angle (90°)

8. 90° (angles in quadrilateral = 360°, so 360° - 85° - 95° - 90° = 90°)

9. Acute angles are less than 90°, obtuse angles are between 90° and 180°
