how do you draw a quadrangle that has at least 1 right angle.
Yes, I can.
There is no specific name for such a shape.
It can be a trapezium, kite, arrowhead, or a general quadrangle. Squares and rectangles also have one right angle - they have more that 1, but that still means they have 1.
well a square has four but it doesnt matter so deal with my opinion
it will have 4 or more sides and 1 or more square thing at a corner
Draw a square / rectangle, a quadrangle is just a shape with 4 sides, as long as one is a right angle your golden
Two possibilities are a kite, or an irregular quadrilateral with one right angle!
Draw two line segments, AB and BC, meeting at a right angle at the point B. Pick any point, D, in the plane, which is inside angle ABC or its opposite angle. Join CD and AD. Then ABCD will be a quadrangle which meets the requirements.
