The Trapezoid Generator draws a trapezoid to scale from its bases AB and CD: a right trapezoid from the bases and leg DA, an isosceles trapezoid from the bases and height, or any other trapezoid from the bases, height and ∠A. Each side and angle can be labeled with its measure, with text you type such as x, or with nothing, and the bases can be marked parallel with arrows.
Teachers use it for the area of a trapezoid, for finding a slanted leg with the Pythagorean theorem, and for angles between parallel lines. The height is drawn dashed, with a right-angle square where it lands, and the diagonals can be drawn with a name for where they cross.
Copy the figure straight into a test, worksheet or slide, or download it as a PNG or SVG. Printing the page prints just the figure. Share link copies the page’s address with your settings in it, so anyone who opens it sees this exact figure, and presets save settings you use often in your browser. It’s free, with no sign-up.
The same shape: a quadrilateral with exactly one pair of parallel sides, its bases. Teachers in the US call it a trapezoid, and teachers in the UK a trapezium.
Choose Isosceles trapezoid or Trapezoid under Kind and type the two bases and the height h. The height is drawn from D, dashed, with a right-angle square where it meets AB, labeled with its measure; change the label to text such as h, or to nothing.
It opens on a right trapezoid with its slanted leg BC labeled x, ready for a Pythagorean theorem question. Change the label with the button after BC.
Yes. Type sqrt for √, / for a fraction and pi for π. The side is drawn to that length, and labeled the way you typed it.
The settings say which measure to fix and why, and the figure keeps the last trapezoid your measures made until they work again.
