4, one set at each corner.
rhombus
Rectangles are made up of 2 sets of parallel lines, which are perpendicular to one another.
Square
a square or a rectangle
A parallelogram, a square or a rectangle !
A square has both parallel and perpendicular symmetry. It is composed of two sets of parallel lines that meet at perpendicular angles.
2
Yes. There are two sets of sides in a square which are parallel to each other and are perpendicular to the other set. Perpendicular means "at 90 degrees to". Hope this helps you.
there are 2 sets of parallel lines in a square
It is possible for all nine lines to be perpendicular to at least one other line.
A parallelogram has two sets of perpendicular lines. The opposite sides of a parallelogram are parallel to each other, while the diagonals intersect at right angles if the parallelogram is a rectangle or a square. However, in a general parallelogram, the angles are not necessarily right angles, but the two pairs of sides remain parallel.
There is only one set of perpendicular lines in a right triangle; the horizontal line and the vertical line that make it 90 degrees.
rhombus
A square has four sets of parallel lines.
Each of the eight line segments is perpendicular to 2 line segments. So there are 8 pair in all.
Two different sets.
A diamond shape, or rhombus, has two pairs of perpendicular lines. The diagonals of the diamond intersect at right angles, creating four right angles at the intersection point. Thus, while there are two sets of diagonals, the key perpendicular lines are the diagonals themselves.
