What is the precise definition of the figure in the image?
Option #1: two lines that intersects at a 90-degree angle
Option #2: two lines that never intersect and are the same distance apart
Option #3: two lines that intersect at a vertex point
The precise definition of the figure in the image is a "right angle" formed by two lines that intersect at a 90-degree angle.
