Find Endpoint Given Midpoint and One Endpoint 

Great video I was looking for this, thank you!!

Thanks so much, I really needed this, I appreciate it!

Thank you so much for the vid this helped me with my pre ap geometry class and I got some helpful notes out of this too!

My teacher shows me a way with just the equation, almost like substituting i think, could you expand?

you made so less complicated thanks!!!

Help me to in this @sir. Question: in triangle ABC , coordinates of the midpoints of line segments AB, BC and AC are (1;2),(4;1) and (2; -2) respectively. Determine the equation of the line segment AB.

Why would the 2 cancel out?

Thanks
