All angles are…
Summary of Shape KeysZ is AIA congruent
X is Vertical Angles VA congruent
Same side of Step Ladder Corresponding angles CA congruent
C or U is Same Side Interior Angles SSI Supplementary
Remember I C U
One acute and One Obtuse then Supplementary
Both angles acute then congruent.
Both angles obtuse then congruent.
Branch off line means supplementary.
