Question

what is the precise definition of the figure in the image? 5 points a straight line that has no thickness and extends infinitely in two opposite directions a part of the circumference of a circle or other curve that measures the distance between two - points on a curve a straight line that always remains the same distance from another line and, therefore, never intersects it a line that intersects another line at a 90 - degree angle

Explanation:

Step1: Analyze the figure

The figure shows two lines \(u\) and \(l\) intersecting at a 90 - degree angle.

Step2: Match with definitions

A line that intersects another line at a 90 - degree angle is a perpendicular line.

Answer:

A line that intersects another line at a 90 - degree angle.
