## Intro to Geometry & Lines and Angles

Summary

The content provides a foundational understanding of geometry concepts crucial for the GRE exam, focusing on lines, angles, and their properties, including the significance of drawing and physically manipulating shapes for better comprehension.

- Geometry involves the study of shapes, and developing visual skills can enhance understanding, especially through drawing and building shapes.
- Lines are straight and infinite, with the importance of not confusing straight lines with horizontal or vertical ones.
- Angles are formed between lines or segments, measured in degrees, and understanding the dynamic nature of angles is essential.
- Key concepts include line segments, angle bisectors, perpendicular bisectors, and the properties of angles such as supplementary and vertical angles.
- Parallel lines and the angles formed when intersected by a transversal are discussed, highlighting the equalities and relationships between these angles.

The GMAT in its current form will be offered through early 2024. Starting on November 7, 2023, a new, shorter version of the exam called the GMAT Focus will become available.

**All Geometry lessons apply to the current GMAT only.** (The GMAT Focus edition does not test Geometry.)
