A rectangle and a square
If you are not a square then you are a rectangle.
A parallelogram has 2 pairs of parallel lines and in the form of a rectangle it has 2 pairs of parallel lines and 4 perpendicular lines that meet at each of its corners at right angles.
A rectangle.
A parallelogram.
None
Square
Perpendicular lines = lines which are at right angles (90 degrees) to each otherDiamond = 2 pairs of parallel lines
12 faces. The number of parallel lines will depend on whether or not the prism is regular and right. In a regular right prism there are 10 parallel edges along the "length". 10 parallel lines make 45 pairs (1-2, 1-3, 1-4, ... 2-3, 2-4, ... etc). Each line at a base has one parallel line at the same base and two at the opposite base. Each such quartet makes 6 pairs of parallel lines and there are 5 such quartets - so 30 pairs of parallel lines in the bases. That makes a grand total of 75 pairs of parallel lines.
rhombus
A shape that has 4 right angles and 2 pairs of parallel lines is a rectangle. In a rectangle, all four angles are right angles, meaning they measure 90 degrees each. Additionally, opposite sides of a rectangle are parallel, resulting in two pairs of parallel lines within the shape.
A square has 4 equal sides, 2 pairs of parallel sides and 4 right angles.
It is called a Rhombus.
