Draw the following trapezoids. If it is not possible, explain why.

a. a trapezoid with one right angle

b. a trapezoid with two right angles

c. a trapezoid with three right angles

d. a trapezoid with four right angles

A. Is always possible just as long as 2 lines are parallel.

b. two right angles but then you can get a diamond if the right angles are opposite each other.

c. If three angles are right angles then the fourth one will be as well and you get a rectangle which technically is not a trapezoid.

d. See comment for answer c.
