Here is how the word, "Rectangle" is broken down: 'Rect' is from the German for 'Right', which in geometry means 90 degrees. And angle is just angle. Together the are 'Rectangle. All 4 angles in a rectangle or 'right', or 90 degrees.
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.
only right tringles or HL triangles have at least 1 right angle
False. Not all quadrilaterals have at least one right angle. While some quadrilaterals, like rectangles and squares, do have right angles, others, such as trapezoids, parallelograms, and rhombuses, may not have any right angles at all. Quadrilaterals can take on various shapes and angles, so the presence of a right angle is not a requirement.
how do you draw a quadrangle that has at least 1 right angle.
no
trapezoid
No.
yes every parallelogram has at least 1 right angle
trapezoid
Yes, I can.
No. A trapezoid need not have any right angles.
A square has to have all 4 right angles, by definition
