Understanding Angle Relationships
Angle relationships are the connections and properties that exist between different angles in geometric figures. Here are some primary types of angle relationships:
1. Complementary Angles
- Complementary angles are two angles that sum up to 90 degrees. For example, if one angle measures 40 degrees, the other must measure 50 degrees.
2. Supplementary Angles
- Supplementary angles are two angles that add up to 180 degrees. For instance, if one angle is 110 degrees, the supplementary angle will be 70 degrees.
3. Vertical Angles
- Vertical angles are the angles opposite each other when two lines intersect. These angles are always equal. For example, if two intersecting lines form one angle measuring 45 degrees, the opposite angle will also measure 45 degrees.
4. Adjacent Angles
- Adjacent angles are two angles that share a common side and a common vertex but do not overlap.
5. Linear Pairs
- A linear pair consists of two adjacent angles that are supplementary. This means they form a straight line when combined.
