Guided Notes
Key concepts students will learn:
- •
To find a point that is one-fourth of the way between two points, first find the midpoint between the two points, then find the midpoint between the starting endpoint and the midpoint you just found.
- •
When finding a point one-third of the way, you must first find the midpoint between the given endpoint and the point that is one-third of the way through.
- •
After finding the midpoint, you can use that point and the point one-third of the way to solve for the midpoint of the line.
