Introduction to Geometry

The video introduces geometry as a language, starting with points, line segments, lines, and rays. It explains how to name rays and discusses special relationships between lines, such as intersecting, parallel, and perpendicular lines. The video concludes with a challenging problem that involves identifying these relationships in a diagram.

What are intersecting lines and how do they relate to right angles?

How can you identify whether two lines are perpendicular?

What defines parallel lines in geometry?
