a. 10 through 25 and 40 through 45
b. 10 through 25 and 40 through 50
c. 0 through 10 and 25 through 40
d. 10 through 50

Which is a logical conclusion based on the given information? a. figure abcd is a rhombus by the definition of a rhombus. b. segment ac is congruent to segment dc by cpctc. c. angle acb is congruent to angle adc by the angle-side-angle theorem. d. triangle acd is congruent to triangle cab by the hypotenuse-leg theorem.
