It could be a kite or an irregular quadrilateral.
A right trapezoid has exactly one pair of perpendicular lines and is a quadrilateral.
One pair of perpendicular lines would create one right angle. Some kites have one right angle.
A trapezoid
A quadrilateral with only one pair of parallel lines is called a trapezoid.
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 trapezoid has exactly one pair of parallel lines
One pair of perpendicular lines would create one right angle. Some kites have one right angle.
a pair of intersecting lines that are perpendicular
Lines that intersect at 90 degrees are perpendicular lines
To prove that a quadrilateral is a right trapezoid, you need to show that it has one pair of parallel sides and one pair of right angles. This can be done by using the properties of parallel lines and perpendicular lines.
trapezium
No parallel lines but a right angle triangle has perpendicular lines.
