The video tutorial explains how to draw and classify a quadrilateral that remains unchanged by reflection over the line y = 3 - x. It starts by plotting given points and drawing the reflection line. The tutorial then demonstrates how to reflect these points over the line to form a quadrilateral. Finally, it classifies the quadrilateral as a trapezoid due to one pair of parallel sides.

What are the coordinates of the two given points of the quadrilateral?

• (1, 9) and (2, 4)

• (0, 8) and (3, 5)

• (1, 8) and (2, 5)

• (0, 9) and (3, 4)
