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.

What does the first number in an ordered pair represent?

• Rotation along the X axis

• Rotation along the Y axis

• Angle of rotation

• Distance from the origin

If a point is represented as (4, -3), how would you move on the coordinate plane?

• Right 4 spaces, down 3 spaces

• Left 3 spaces, down 4 spaces

• Left 4 spaces, up 3 spaces

• Right 3 spaces, up 4 spaces

Which of the following is a correct interpretation of the point (-6, 4)?

• Move 6 units to the right and 4 units up

• Move 6 units to the left and 4 units up

• Move 4 units to the right and 6 units down

• Move 4 units to the left and 6 units down

What is a key characteristic of a rectangle that helps in finding a missing vertex?

• Diagonals are perpendicular

• All angles are 45 degrees

• All sides are equal

• Opposite sides are parallel and congruent

How many 90-degree angles does a rectangle have?

• Four

• None

• Three

• Two
