Question

Need help ASAP due at 11

Got some of it done need help with identifying why BC and AD are parallel

Answer 1

Explanation:

the arrows on the lines EC and AB mean those are parallel, also the tick marks on AD and AB mean those are the same length, so two adjacent sides are the same length and two opposite sides are parallel. This is a rhombus, or a tipped square. So now we know, sides AD and BC are also parallel
