Question

Help me please its geometry

Answer 1

Answer for the first dropdown box is CAF and EFH

Answer for the second dropdown box is because they are corresponding angles of parallel lines cut by a transversal

Answer for the third dropdown box is transitive property of congruence

------------------------------------------------------------------------------

Explanation:

Angles CAF and EFH are corresponding angles because they are on the bottom side of the parallel lines, and on the right side as well. So they are congruent (due to the lines being parallel). 

Since CAF = EFH and EFH = HFD, this means that CAF = HFD

It's similar to saying if x = y and y = z, then x = z. Think of it as a connecting chain. This is the transitive property.
