Question

How to identify pairs of angles

Answer 1

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
