    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.
    • 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.
