Answer:
When a pair of parallel lines is cut with another line, known as an intersecting transversal, it creates pairs of angles with special properties.
Explanation:
CORRESPONDING ANGLES are equal
<1 and <5 <2 and <6 <4 and <8 <3 and <7
ALTERNATE INTERIOR ANGLES are equal
<3 and <5 <2 and <8
ALTERNATE EXTERIOR ANGLES are equal
<1 and <7 <4 and <6
VERTICALLY OPPOSITE ANGLES are equal
<5 and <7 <6 and <8 <1 and <3 <2 and <4
COINTERIOR ANGLES are supplementary, meaning adding their measurements together will give you 180°
<2 and <5 <3 and <8
