How do you draw a quadrilateral with 1 reflex 1 obtuse and 2 acute angles?

Well, honey, to draw a quadrilateral with 1 reflex, 1 obtuse, and 2 acute angles, you'll need to start by sketching a shape with 1 angle greater than 180 degrees (that's your reflex angle), 1 angle greater than 90 degrees (that's your obtuse angle), and 2 angles less than 90 degrees (those are your acute angles). Just make sure all the angles add up to 360 degrees, and you'll have yourself a sassy quadrilateral!
