7.2 Angle Properties of Parallel Lines
A line that intersects a pair of parallel lines is called a transversal. When angles
are formed by two parallel lines and a transversal:
Corresponding Angles
are equal
“F Pattern”
Alternate Angles
are equal
“Z Pattern”
Interior Angles have a
sum of 180°
“C Pattern”

Let’s find the corresponding, alternate and interior angles:
Corresponding Angles (F Pattern):
c = d =
e = f =
Alternate Angles (Z Pattern):
e = f =
Interior Angles (C Pattern)
e + ___ = 180° f + ___ = 180°
