Prove Triangle BEC is congruent to triangle DCF.[Solved]

WebSo, ∠ACD = ∠DCF = 60° CE = External angle bisector of ∠DCF So, ∠DCE = ∠ECF = 30° ∠BCE = ∠BCA + ∠ACD + ∠DCE ⇒ 60° + 60° + 30° ⇒ 150° In ΔBCE, ∠EBC + ∠BCE + ∠CEB = 180° ⇒ 15° + 150° + ∠CEB = 180° ⇒ 165° + ∠CEB = 180° ⇒ ∠CEB = 180° – 165° ⇒ ∠CEB = 15° ∴ Value of ∠CEB is 15° Tips and Tricks: ∠CEB = ∠BAC/4 ⇒ 60°/4 = 15° … Web26 mrt. 2016 · Reason for statement 8: If two angles are supplementary to two other congruent angles, then they’re congruent. Note: Depending on where your geometry teacher falls on the loose-to-rigorous scale, he or she might allow you to omit a step like step 6 in this proof because it’s so simple and obvious.
