In this lesson, you will learn how to identify lines, rays, and planes in geometry. A point is simply a location in space with no size or dimension. A line is a collection is points that extends in both direction infinitely. A plane is a 2D surface where all lines and points lie. Lines, rays, points, and lines are important to geometry because all topics beyond this are built upon these topics. For example, when we get to triangles and triangle similarity we need to know that the sides of the triangle are made up of line segments. Also, when studying angles, we need to know that the two sides of the angle are composed of rays in geometry.

It's definitely a lesson that I've been looking for for a while. I am very grateful to my dear teacher for asking me to add more lessons about oppression. It's definitely a lesson I'll never forget. Thank you teacher 🙏🙏🙏👍👍👍 💕😘💕😘
You are an awesome Math Teacher. I plan to take a nursing exam and your videos have been extremely helpful. Jason, when you teach I am able to understand, your teaching skills are perfectionist. Thank you!!!!

Thanks so much!
If this man taught you something Einstein would have nothing on you....
Jason you're the best. Do you have any plans to try another programming course like C or C++? Your java one got me started and I loved it. I paid for the website subscription for 6 months across 2 different years as well.
Extremely interesting lesson with good and remarkable examples. Thank you )

nuh uh
however "just a dot" is a rather inaccurate description of a point... You can mention Euclid's Elements start with ""A Point is that which has no Parts or Magnitude." Point, Line are technically "undefined" though everyone has good idea what they are...
