Yes, 2 is congruent to 4 because they are vertically opposite anges

And YES  1 and 2 are adjacent supplementary angles.

They are adjacent because they share  a commone vertex and a common arm.

 

adjacent is just a normal English word.  You house is on your property and the adjacent property is the one that shares a fence line with yours. :)

 

Supplementary means add to 180 degrees

Complementary means add to 90 degrees

You never need to muddle these up because 1 S is mad of 2 C's  .  (one is back to front and on top of the other)   

Do you understand what I mean?
