The Main Types of Angle Relationships
1. Complementary Angles
Complementary angles are two angles that add up to 90°.
Example: 30° + 60° = 90°
Think of them as two pieces making a perfect corner.
2. Supplementary Angles
Supplementary angles are two angles that add up to 180°.
Example: 110° + 70° = 180°
Together, they form a straight line.
Easy Memory Trick: Supplementary = Straight line
3. Vertical Angles
Vertical angles are the opposite angles formed when two lines cross.
The important rule: Vertical angles are always equal.
Example: If one angle is 45°, the angle directly across from it is also 45°.
4. Adjacent Angles
Adjacent angles are angles that:
- Sit next to each other
- Share a common side and vertex
They’re basically “neighbor angles.”
Example: Pizza slices sitting side by side are a great real-world example.
5. Linear Pairs
A linear pair is a special type of adjacent angle.
They:
- Sit next to each other
- Form a straight line
- Always add up to 180°
Quick Shortcut: If one angle is 140°, the other must be:
180° – 140° = 40°
