Answer: a) AE || BC b)AB=BC c)AE⊥ED &ED⊥CD
Explanation:
a) The line segments that have the arrow sign on them mean that they are parallel, so AE || BC ( || = parallel to).
b) When two line segments have a dashed line on it, it shows that they are the same length, so AB is equal to BC.
c) when two segments intersect with a 90° angle, they are perpendicular, so AE⊥ED &ED⊥CD(⊥ = perpendicular to).
