Why is any pair of adjacent angles formed by two intersecting lines always equals 180 degrees?

Because if you draw a line though a circle, cutting it in half, as a circle is 360 degrees there must be 180 above the line and 180 below.
As any line cutting another line simply divides the 180 degrees belonging to that side of the line, any adjacent angles MUST add up to 180 degrees.

How are the adjacent angles formed by intersecting lines related?
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
What describes angles formed by 2 intersecting lines?
Opposite angles are equal. Adjacent angles add up to 180 degrees.
Is this statement true or falseVertical angles are the non-adjacent angles in a pair of intersecting lines.?
true
How do you construct adjacent congruent angles?
Draw to lines intersecting each other. The angles across from each other will be both congruent and adjacent
What are two adjacent angles whose measures are always supplementary?
Two right angles would always be supplementary because the sum of their angles is 180 degrees.
How are the adjacent angles formed by intersecting lines related?
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
The nonadjacent angles formed by two intersecting lines?
two adjacent angles formed by two intersecting tines are
What describes angles formed by 2 intersecting lines?
Opposite angles are equal. Adjacent angles add up to 180 degrees.
Two nonadjacent angles formed by two intersecting line are called?
Two angles that aren't adjacent but are formed by intersecting lines are called vertical angles. Their angle measures are always equal.
Is the sum of the measures of the angles of a self-intersecting quadrilateral always 360 degrees?
The interior angles of a quadrilateral always add up to 360 degrees.
What is a non adjacent angles formed by two intersecting lines?
When two lines intersect four angles are formed. Adjacent refers to angles that are next to each other so non adjacent refers to the ones opposite each other. They will have equal angles. Two adjacent angles in this situation will have a sum of 180 degrees.
What TYPE are angles of pairs of opposite and congruent angles formed by intersecting lines?
Adjacent angles
Two non adjacent angles formed by two intersecting lines?
Verticle angles
What is a non-adjacent angle formed by intersecting lines?
A pair of intersecting lines form adjacent and opposite angles. So the answer to the question is an opposite angle.
What are angles formed by two intersecting lines and only share one vertex?
adjacent angles
Is this statement true or falseVertical angles are the non-adjacent angles in a pair of intersecting lines.?
true
How do you construct adjacent congruent angles?
Draw to lines intersecting each other. The angles across from each other will be both congruent and adjacent
