No parallel lines but a right angle triangle has perpendicular lines.

a square
A shape with no right angles and one pair of parallel lines would be called a trapezoid in the USA, and a trapezium in Britain.
1 pair
A trapezium can have right angles as long as there is at least one pair of parallel lines.
trapezoid
Perpendicular lines
NO !!! A triangle consists of three non-parallel lines.
for a shape to be parellel two lines have to never touch if they were extended on forever. a shape with one pair of parellel lines is a trapezoid.
The lines that meet at right angles are perpendicular to each other.
A trapezoid has one pair of parallel side and can have two adjacent angles that are right.
