Answer:
Step-by-step explanation:
Given:

To Prove:
AB║DE
Solution:
Since, corresponding sides of ΔACB and ΔDCE are proportional,

Both the triangles will be similar.
ΔACB ~ ΔDCE [By SAS property of similarity]
Therefore, ∠1 ≅ 2 [CPCTC]
Since, ∠1 and ∠2 are the corresponding angles
Therefore, AB║DE [Converse of corresponding angles theorem]
50% because 1/2 is one half and 1/2 is 50%
They gave the coordinates so you are going to use distance formula to find the MN.
