Determining Unknown Ordered Pairs

The video tutorial teaches how to determine unknown ordered pairs using polygon characteristics. It begins with an introduction to ordered pairs and their representation on the X and Y axes. The tutorial then explains how to plot points on a graph using ordered pairs. It discusses the properties of rectangles, such as congruent and parallel sides, and 90-degree angles, to find a missing vertex. The lesson concludes by applying these properties to locate the last vertex of a rectangle.

Explain the significance of opposite sides being congruent in a rectangle.

What does it mean for sides of a rectangle to be parallel and perpendicular?
