Question 252136: Given: ∠DCE is congruent to ∠CDE which is congruent to ∠DEC; ∠CDB is congruent to ∠CBD
Complete the proof.
Prove: BC is congruent to DE
a. DE is congruent to EC is congruent to CD because ___?
b. BC is congruent to DC because ___?
c. ∴ BC is congruent to DE because ___?
i figured that answer a would be because of the definition of equilaterial triangles
