Prove that DAB is congruent to BCD. 1. Angle A is congruent to Angle C. Given
2. Blank. They are lengths of the same segment.
3. AB is parallel to CD. Given
4. Angle ABD is congruent to CDB. When a transversal crosses parallel lines, Blank angles are congruent.
5. Triangle

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.
