As it does not obey the important property of adjacent angles, therefore. both of these parallel lines, we call that a transversal. All angles have relationships to other angles and those angle relationships are what we will cover here. Why don't we just put two lines between parallel line like this || to signal that they are parallel? equal right over here. Remember, too, the relationships still hold when the lines cut by the transversal are not parallel; you just cannot use Theorems to make assumptions about the angles. The size of the angle xzy in the picture above is the sum of the angles A and B. Step-by-step explanation: Sana makatulong : ) Advertisement The more restrictive our intersecting lines get, the more restrictive are their angle relationships.
