Exploring Polygons in a Coordinate Plane

This video tutorial covers section 8.6 on polygons in a coordinate plane. It explains how to use ordered pairs to represent vertices and draw polygons. The tutorial includes examples of drawing a quadrilateral and finding distances between points using absolute values. It also demonstrates calculating the perimeter and area of a rectangle using a coordinate plane.

What does the term 'vertices' refer to in the context of polygons?

• The corners of the polygon

• The highest point of the polygon

• The area inside the polygon

• The center point of the polygon

How many sides does a quadrilateral have?

• Six

• Five

• Four

• Three

When calculating the distance between points with the same y-coordinate, what should you use?

• Subtract the x-coordinates

• Add the x-coordinates

• Multiply the x-coordinates

• Divide the x-coordinates

What is the correct method to find the distance between two points in the same quadrant?

• None of the above

• Multiply their coordinates

• Subtract the smaller coordinate from the larger

• Add their coordinates

How do you calculate the distance between points with the same x-coordinate?

• Add the absolute values of the y-coordinates

• Subtract the absolute values of the y-coordinates

• Multiply the absolute values of the y-coordinates

• None of the above

In which quadrant would you add the absolute values of coordinates to find the distance?

• When points are in the same quadrant

• When points are in different quadrants

• When points have the same x-coordinate

• When points have the same y-coordinate

If two points have coordinates (3, -2.5) and (3, -5), what is the distance between them?

• 2.5 units

• 7.5 units

• 1.5 units

• 5 units

What is the perimeter of a rectangle with sides measuring 12 meters and 8 meters?

• 20 meters

• 40 meters

• 96 meters

• 24 meters

How do you calculate the area of a rectangle?

• Length divided by width

• Length times width

• Length plus width

• None of the above

What unit of measurement was used in the example involving an archaeologist?

• Feet

• Meters

• Yards

• Inches
