m∠BEC + m∠CED = m∠BED; Angle Addition Postulate
Step-by-step explanation:
Angle addition postulate says that when we two angles joined such that they have one common line segment or ray then a new angle formed by it.For example : If ∠MON and ∠NOK are joined such that NO is the common line segment between then then the new angle will be ∠MOK or ∠KOM.
In given figure , m∠BEC and m∠CED are joined and they have common line segment CE , then the new angle m∠BED= m∠BEC + m∠CED
Hence, the correct statement that completes the given proof :
m∠BEC + m∠CED = m∠BED; Angle Addition Postulate
