Identify a set of parallel and a set of perpendicular lines in this image.
An image shows that line BF intersects both line AD and line EH at 90 degree angles and that line CG intersects both line AD and line EH at 90 degree angles. At the points of intersections, a right angle symbol is shown to indicate that line BF is perpendicular to line AD and to line EH and line CG is perpendicular to line AD and line EH.
In this image, the set of parallel lines can be identified as line AD and line EH. Both of these lines are horizontal and never intersect each other.
The set of perpendicular lines can be identified as line BF being perpendicular to both line AD and line EH, and line CG being perpendicular to both line AD and line EH. These lines intersect the horizontal lines (AD and EH) at 90-degree angles.
