The question is:

In the following diagram AC=CE and BD=DE .Which of these statements are true ? 1-AB is twice as long as CD 2-AB is parallel to CD 3-Triangle AEB is similar to triangle triangle CED Note: All these statements are correct. 

enter image description here

Could anyone explain how the three statements are correct without using Without Trigonometric ratios especially if there is no link between AE and BE

Edit: I assume we need to use Thales theorem here -
