I think it is either a right triangle, square, pentagon, or rectangle.
The letter "L" in the alphabet has only one pair of perpendicular lines. It consists of a vertical line and a horizontal line that meet at a right angle, forming the distinctive shape of the letter. Other letters may have more lines or curves but do not feature just one pair of perpendicular lines.
A shape that has two parallel lines and no perpendicular lines is a trapezoid, specifically an isosceles trapezoid. In this shape, one pair of opposite sides is parallel, while the other pair is not perpendicular to the parallel sides. This creates a unique geometry without right angles. Another example could be a parallelogram, which also has two pairs of parallel sides but does not necessarily have any perpendicular lines.
A shape with one pair of perpendicular lines is a right-angled triangle. In this triangle, one of the angles measures 90 degrees, which creates the perpendicular intersection of the two lines that form the legs of the triangle. This characteristic defines the right triangle and distinguishes it from other types of triangles.
A plus sign (+) would be a pair of perpendicular line segments.
The lines that meet at right angles are perpendicular to each other.
Trapizium
a pair of intersecting lines that are perpendicular
A right trapezoid has exactly one pair of perpendicular lines and is a quadrilateral.
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.
a triangle, pentagon and that's all i can think of * * * * * A right angled triangle has a pair of perpendicular lines! Likewise, a pentagon can have a pair. A circle, ellipse etc do not.

A right-angle triangle.
Lines that intersect at 90 degrees are perpendicular lines
No parallel lines but a right angle triangle has perpendicular lines.
A plus sign (+) would be a pair of perpendicular line segments.
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
