Adjacent lines are any two lines that meet at a common vertex.
A pair of intersecting lines form adjacent and opposite angles. So the answer to the question is an opposite angle.
Two pairs of adjacent angles are formed when two lines intersect each other.
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
Yes
It means when two lines meet. Parallel lines never meet; they stay exactly the same distance apart.
Yes, any vertex is formed by two adjacent lines.
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
A pair of intersecting lines form adjacent and opposite angles. So the answer to the question is an opposite angle.
Yes, the diameter of the semicircle is adjacent (next) to the arc.
Not aways because they can be perpendicular lines or lines of intersection
A pair of intersecting lines form adjacent and opposite angles. So the answer to the question is an opposite angle.
A rectangle's perpendicular lines are ALWAYS adjacent to eachother
Two pairs of adjacent angles are formed when two lines intersect each other.
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
Yes
Two pairs
No. Consider a set of two or more parallel lines and pick any one of them. There will be another line adjacent to it. But, because it is parallel to the first, they cannot intersect.
