We have proven that BC = DE using the Segment addition postulate
Segment addition postulate
The segment addition postulate states that given two points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC
The reasons for the proof are given below:
Statement Reason
BD = BC + CD Segment addition postulate
CE = CD + DE Segment addition postulate
BD = CE Given
BC + CD = CD + DE Substitution property
BC = DE Subtraction property
Hence, we have proven that BC = DE using the Segment addition postulate
