Spheres do not have any perpendicular lines.
a regular hexagon
Oh, dude, a heptagon has like a bazillion pairs of perpendicular lines... just kidding! It actually has 14 pairs of perpendicular lines. So, like, if you ever need to find perpendicular lines in a heptagon, you've got plenty to choose from.
Two pairs of perpendicular lines are lines that intersect at a right angle (90 degrees). For example, the x-axis and y-axis on a Cartesian coordinate plane are perpendicular to each other. Similarly, the lines represented by the equations ( y = 2x + 3 ) and ( y = -\frac{1}{2}x + 1 ) are also perpendicular, as their slopes multiply to -1.
A cuboid has 12 edges, and each edge is perpendicular to 4 other edges. Thus, in total, there are 12 pairs of edges that are perpendicular to each other. However, if considering distinct perpendicular lines, a cuboid effectively has 3 sets of three mutually perpendicular lines, corresponding to its three dimensions (length, width, and height).
It can be :- 1- a parallelogram 2- Square if diagonals are perpendicular and congruent 3- Rectangle if diagonals are congruent 4- Rhombus if diagonals are perpendicular
