Two lines but they can't be parallel. It would be better to say two rays that share the same endpoint form an angle. However, two intersecting lines form angles also. Two rays can form a 180 degree angle if they share the same endpoint and point in exactly the opposite directions. Two perpendicular lines can form a right or 90 degree angle.
Two lines that form a 90 degree angle are considered perpendicular.

50. It is always two times the rotation.
A line is orthogonal to another if it is at 90° to it. You can call lines that intersect at 90° orthogonallines.You can also say that the lines form a right angle.
When two lines intersect to form a 90o angle, they are said to be perpendicular.

Lines that form a 90 degree angle at their vertex. Two lines that make a 90 degree are perpendicular.

When two lines meet to form an angle the lines are intersecting.
The point where two lines form an angle is called the vertex.
When two lines intersect then the degree is called an angle. This does not work with parallel lines.
