Right Trapezoid

Right Trapezoid

Trapezoid that has at least one right angle.


  • Since a line d perpendicular to a line e is also perpendicular to all the lines parallel to e, then, if a trapezoid has at least one right angle, it always has at least two.
  • The adjacent angles of an isosceles trapezoid that are not right angles are supplementary angles.


This is a right trapezoid with right angles A and D :
