Study Notes
Parallel Lines and Transversals
- Parallel lines are defined as two lines that will never intersect, often identified by arrows on the lines.
- A transversal line is one that intersects two or more lines at different points.
Angles Related to Parallel Lines
- Corresponding angles are located in the same position on the parallel lines relative to the transversal and are always congruent.
- Alternate interior angles are found between two parallel lines on opposite sides of the transversal and are also congruent.
- Consecutive interior angles occupy the same side of the transversal and are positioned between two parallel lines.
Basic Angle Concepts
- An angle is formed by two rays that share a common endpoint, known as the vertex.
- The vertex of an angle is represented by the middle letter when naming the angle.
Angle Naming and Relationships
- Angles can be named using just the vertex if it is the unique angle located at that vertex.
- Vertical angles occur across from each other when two lines intersect and are always congruent.
- Adjacent angles are two angles that share a common vertex and a side, positioned next to each other.
Angle Measurements
- Complementary angles are pairs of angles whose measures add up to 90 degrees.
- Supplementary angles are pairs of angles whose measures total 180 degrees.
