Refer to the figure below. Make use
of Euclid's axioms and postulates.
Line AB crosses lines CD and EF.
Angles 1, 2, 3, and 4 are the angles
formed by intersecting lines AB & CD.
Angle 2 is greater than 90°.
Angles 5, 6, 7, and 8 are the angles
formed by intersecting lines AB and
EF. Angle 7 is a right angle.
