Question

is the image an example of perpendicular lines?
a
b
yes, the lines intersect.
yes, the lines intersect at a right angle.
no, the lines never touch.

Explanation:

Perpendicular lines are defined as lines that intersect at a right angle (90 degrees). In the given image, there is a right - angle symbol where the two lines intersect. Just intersecting is not enough for perpendicularity (as lines can intersect at other angles). And the lines do touch (intersect), so the "never touch" option is incorrect.

Answer:

Yes, the lines intersect at a right angle.
