parallel line angles
the powerpoint for this topic is here
it needs to be downloaded for the animations to work
Z angles can be established from a 180 degree rotation
(Z is at the opposite end of the alphabet from A (alternate))
the angles are alternate sides of the transversal
F angles can be established from a translation
(F,C (corresponding) football club)
the angles correspond because one slides onto the other
see also parallel line angle relationships and proofs here
