∠3 Near D

∠2 Near E

∠1  Near A

Right angle = 90°

∠ECD

∠ECB

Adjacent angle pairs

∠1 and ∠3   Near A

∠4 and ∠2   Near A

∠3 and ∠1    Near D

∠2 and ∠4   Near D

∠2 Near B and ∠2 Near A

∠1 Near B and ∠1 Near A

∠4 Near D and ∠4 Near A

∠1 Near D and ∠4 Near A

∠2 Near E and ∠4 Near D

∠1 Near E and ∠4 Near A

Obtuse angle = Greater than 90°

∠2 Near D

∠1 Near E

∠4 Near D

This was a long one!

I hope this helped :)
