## Lines and Angles

Summary

The content provides a foundational understanding of geometry, focusing on lines, angles, and their properties, essential for GRE exam preparation.

- Geometry involves the study of shapes, requiring visual skills and hands-on practice for better understanding.
- Lines are straight and infinite, with line segments being finite parts of lines, and angles are formed by the intersection of lines or segments.
- Key concepts include the properties of straight angles (180 degrees), right angles (90 degrees), supplementary angles, and perpendicularity.
- Congruency and bisectors play significant roles in geometry, with congruent shapes having identical form and size, and bisectors dividing angles or segments into equal parts.
- Understanding the relationships between angles, especially in the context of parallel lines and transversals, is crucial for solving geometry problems on the GRE.
