Please someone help, give the right answer it’s important

Honestly, I'm finding it difficult to formulate a sentence to justify the reasons. All I can say is that statement 2,3,4, and 5 are right.

maybe to give a reason, you can say:

2) Reason: the length of line AD is equal to the sum of the length of lines AC and CD.

You can go ahead and answer the rest of the questions like that.

I hope it helps
