The pairs of lines are nothing but the two lines, which may be intersects or parallel or perpendicular as shown below: Angles: The region between two infinitely long lines pointing a certain direction (ray) from a common point (or vertex) is termed as an angle. ... The symbol for an angle is “ ∠ ”.

Answer:
Properties of Lines
Collinear points are a set of three or more points which lie on the same line.
The points which do not lie on the same line are called non-collinear points.
Properties of Angles
An angle is a figure in which two rays emerge from a common point. This point is called the vertex of the angle and the two rays forming the angle are called its arms or sides.
An angle which is greater than 180 degrees but less than 360 degrees is called a reflex angle.
If two adjacent angles add up to 180 degrees, they form a linear pair of angles. In the following figure, ∠a and ∠b form a linear pair.
When two lines intersect each other, the two opposite pairs of angles formed are called vertically opposite angles. In the following figure, ∠A and ∠B are vertically opposite angles. Another pair is ∠C and ∠D.
