The video tutorial explains how to plot points of a quadrilateral and analyze its properties. It covers reflections over the lines y = x/2 and y = -2x + 5, demonstrating how these reflections leave the quadrilateral unchanged. The tutorial further explores the construction of the quadrilateral by reflecting points and verifies its properties, such as parallel sides and perpendicular diagonals, to determine if it is a rhombus.

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

• (4, -2) and (5, 0)

• (-4, 2) and (5, 0)

• (4, 2) and (0, -5)

• (-4, -2) and (0, 5)
