given the diagram, we need to find the length of segment BC well, Point D has got congruent markings on each side of Point D. So Point D is the midpoint of a C point. E also has come group markings on each side of Point E, making E the midpoint of Segment A B that makes Segment D E E, the mid segment of Triangle ABC parallel to side BC and the mid segment there. Um, says any mid segment is 1/2 its parallel side. We can rewrite this and say two times the length of D E is equal to B. C, and we are given that D is the length 2.3, which allows us to find the measurement of segment BC.
