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.
It is possible for all nine lines to be perpendicular to at least one other line.
there are 2 sets of parallel lines in a square
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.
Rectangles are made up of 2 sets of parallel lines, which are perpendicular to one another.
A square, a rectangle, a rhombus and a parallelogram are 4 sided quadrilaterals that have 2 sets of parallel lines.
