2. Lines, Line Segments, and Rays By Mr. Bales

3. Objective By the end of the lesson, you will be able to identify, describe, and classify lines, line segments, and rays.By the end of the lesson, you will be able to identify, describe, and classify lines, line segments, and rays. Standard 4MG3.1 - Students will identify lines that are parallel and perpendicular.Standard 4MG3.1 - Students will identify lines that are parallel and perpendicular.

4. What in the World are Lines? A line is a group of points on a straight path that extends to infinity.A line is a group of points on a straight path that extends to infinity. You would label this AB or BAYou would label this AB or BA A B

5. Thank you Andrew for Asking about Line Segments!! A line segment is a part of a line that has two end points.A line segment is a part of a line that has two end points. How many end points Natalie?How many end points Natalie? The two end points of the line segment are used to name the line segment. This line segment is called segment XY or YX.The two end points of the line segment are used to name the line segment. This line segment is called segment XY or YX. XY

6. Wow! Great Question Ty!! He asked, “What are Rays? A ray is part of a line. It has one end point and extends to infinity in one direction.A ray is part of a line. It has one end point and extends to infinity in one direction. A ray is named starting with its end point first and then any other point on the ray second.A ray is named starting with its end point first and then any other point on the ray second. So, it would be labeled CDSo, it would be labeled CD C D

7. Pop Quiz!!!! No Need to Thank Me! It’s My Pleasure! What is this called….What is this called…. What is this called…What is this called… AB Can you label it correctly? XY GH

8. Types of Lines We can describe lines, rays, and line segments by the way they meet or cross each other.We can describe lines, rays, and line segments by the way they meet or cross each other. Let’s hear from someone know as they describe a couple of line segments.Let’s hear from someone know as they describe a couple of line segments. Mrs. Benson!!Mrs. Benson!!Mrs. Benson!!Mrs. Benson!!

9. Parallel Lines Parallel lines are always the same distance apart. They never meet.Parallel lines are always the same distance apart. They never meet. AB ll CDAB ll CD A BC D

10. Intersecting Lines Lines that meet or cross each other are called intersecting lines.Lines that meet or cross each other are called intersecting lines. AB intersects CDAB intersects CD A B C D

11. Perpendicular Lines Lines that meet or cross each other to form right angles are called perpendicular lines.Lines that meet or cross each other to form right angles are called perpendicular lines. AB CDAB CD A D C B
