In this lesson I will teach you more about quadrilaterals, triangles and there midpoints. As you can tell there is a lot of information you need to learn about quadrilaterals and triangles and each theorem and property is important. Hence you need to remained focused on all the details I explain in the video and ensure you are taking great notes. One of the things I will talk about in the lesson is what happens when a transversal (a line) intersects parallel lines- especially if the transversal is cut into congruent segments. Also I will get into what a midpoint of a triangle is and the relationship it forms with the sides of a triangle. If you have been going through the lessons in this course in order you already have increased your knowledge of triangles significantly. Additionally you know a lot of powerful theorems about parallel lines and various quadrilaterals. But as you will see in future lessons we have a lot more to learn on these and other topics so stay excited and practice as much as you can. Good luck!
