(shown on the projector is a hand-drawn quadrilateral of red lines with A marked in the top left, B on the rop right, C on the bottom right, and D for the bottom left (as for the square equivelent))
Student: Line AD, and line BC are parallel.
Teacher: These lines are parallel?
Teacher: If these lines were extended, would they cross over each other?
(Teacher extends the lines by drawing a dashed line so that there is a clear intersection at 50% more than the polygon distance)
Teacher: These lines are parallel, right?
Teacher: Do you know what a parallel line is?
Student: Two lines that never cross over each other.
Teacher: Then, do these lines cross over each other.
Teacher: Then are these lines parallel?
