I don't think it is midpoint. My understanding is that we are looking for the two segments of the line that are in a specific ratio. If the total length is provided we can then locate the point that divides the line segment into the given ratio.

Subject: common core geometry question


Has anybody started to write curriculum for the common core High School

courses?



Here is one standard for Geometry : G.GPE.6 Find the point on a

directed line segment between two given points that partitions the

segment in a given ratio.







Do you think this means find the midpoint? (that is what I found on one

website)



or they have to find a point between two given points such that the

ratio of the segments is 3:4 (for example) ? What do they expect the

students to do to find this out?



Anybody???
