**Intro to Geometry & Lines and Angles**

**Next Lesson**

Summary

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

- Geometry involves the study of shapes, and developing visual skills can enhance understanding.
- Lines are straight and infinite, and it's crucial not to confuse straight lines with horizontal or vertical ones without explicit information.
- Angles are formed between two lines or segments, measured in degrees, and understanding their properties, such as being supplementary or congruent, is vital.
- Bisectors divide angles or segments into two congruent parts, with perpendicular bisectors also being equidistant from the segment's endpoints.
- Understanding the relationships and properties of parallel lines and the angles formed when they are intersected by a transversal is crucial.

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.)
