Line e bisects line xy at m and divides line xy into two equal parts. name a pair of congruent segments.

Xm and MY.

you are given two segments, AB with AB= 4 and CD with CD = 7. you want to construct a new segment, EF, with EF = 1. If you use only congruent segments construction, explain how you can use AB and CD to construct EF ?

i don't know!!!
