Draw the first two sides of any rectangle. Then from the free ends draw two lines which meet quite close the the corner you have drawn.

A bit like a chevron or an arrowhead.

Yes I had a question on my maths test asking me to draw a quadrilateral with one right angle, so yeah, a quadrilateral can have exactly one right angle lol But i havent got a clue how to draw one :S

If you have a 360o protractor, you draw one side of the angle, measure 245o round from this line and then draw in the other side of the angle, and then mark a small arc around the reflex angle. If you only have a 180o protractor, you start again by drawing one side of the angle; then you measure 360o - 245o = 115o the "wrong way" round from this line to give the 245o the right way and draw in the other side, and then mark a small arc around the reflex angle.

An arrow head that is flat at tip instead of pointy.

A reflex angle is one that is more than 180 degrees but less than 360 degrees. If the reflex angle measured 190 degrees, then there would be a 170 degree, or obtuse, angle opposite it. If the reflex angle measured 270 degrees, then there would be a 90 degree, or right, angle opposite it. If the reflex angle measured 300 degrees, then there would be a 60 degree, or acute, angle opposite it. It helps to draw or picture these angles as sectors of a circle.

No.

This is an arrowhead quadrilateral.

When an angle is drawn a small arc is normally placed near the vertex between the arms to show the angle. A reflex angle is one greater than 180°, so draw the two arms as normal and then draw a small arc around the vertex of the angle "outside" the arms of the angle, ie around the angle which is greater than 180° If the problem is how to draw the reflex angle with a protractor that only goes up to 180°, then note that "360° - the reflex angle" gives an angle which is less than 180° and can be measure by the 180° protractor. Draw one arm of the angle, measure the calculated angle (eg if the reflex angle was 200°, 360° - 200° = 160°, so measure 160°), draw the other arm, and then draw an arc around the vertex "outside" the arms to show the reflex angle (in the example, the 200° angle).

A chevron.

A reflex angle is over 180 degrees, but the sum of the angles in a quadrilateral, concave or convex, is 360. Therefore, since 180+180=360, you can't have any more degrees even without the amount over 180 that the reflex angle has.

A reflex angle is an angle greater than 180 degrees and less than 360 degrees. To construct one draw two lines at an angle and draw the angle measurement circle around the side you normally don't do it on.

Yes. One. The quadrilateral then looks a bit like a boomerang, according to my daughter. We had to establish this answer in her year 7 maths homework.
