Exploring Lines, Line Segments, and Rays in Geometry

This video tutorial explores the differences between line segments, lines, and rays in geometry. It explains that a line segment has a starting and stopping point, a line extends infinitely in both directions, and a ray has a starting point but extends infinitely in one direction. The video also includes a practice module from Khan Academy to help recognize these geometric concepts.

What is the main focus of this video?

• The definition of polygons

• The concept of angles

• The properties of circles

• The difference between a line segment, a line, and a ray

Why do we call it a 'segment'?

• Because it is a part of a circle

• Because it has a starting and stopping point

• Because it is curved

• Because it goes on forever
