7.3 Partitioning a Segment

Front

What is the definition of partitioning a segment?

Back

Partitioning a segment refers to dividing a line segment into smaller segments in a specific ratio.

What does the ratio 3:1 indicate when partitioning a segment?

Back

It indicates that the segment is divided into 4 parts, with one part being three times longer than the other.

How do you find the coordinates of a point that partitions a segment in a given ratio?

Back

Use the section formula: P(x,y) = ((mx2 + nx1)/(m+n), (my2 + ny1)/(m+n)) where m:n is the ratio.
