Question

identifying lines mastery check which figure is an illustration of perpendicular lines? a b

Explanation:

Step1: Recall perpendicular - lines definition

Perpendicular lines intersect at a 90 - degree angle.

Step2: Analyze Option A

The lines in Option A intersect at an angle other than 90 degrees.

Step3: Analyze Option B

The lines in Option B are parallel, not perpendicular.
Since no correct figure is shown in the provided options, we assume there is a missing correct option or an error in the presentation. But if we assume a standard perpendicular - lines situation where two lines intersect at a right - angle, we need to look for lines that form a square - corner intersection.

Answer:

No correct option shown among A and B.
