text: true or false? given: ac= 1/2 ab. conjecture: <abd=<cbe? the equal sign is supposed to be a congruent symbol the conjecture is false.  c *could* be the midpoint of ab, but not necessarily. c could be anywhere on the circle of radius 1/2ab whose center is on point a. hence, it's possible for c to be the midpoint, but it could be elsewhere as well.
