Geometry Concepts on Coordinate Plane

The video tutorial covers the basics of polygons on the coordinate plane, focusing on finding the perimeter and area. It begins with an introduction to polygons and vertices, explaining their properties and representation on the coordinate plane. The tutorial then demonstrates how to calculate the perimeter by finding the distance between points and summing them up. It also covers methods to find the area by breaking down complex shapes into simpler ones and using formulas. The video encourages students to practice these concepts independently.

What is a polygon?

• A shape with only two sides

• A closed figure with three or more line segments

• A shape with no vertices

• A figure with curved lines

How are vertices represented on a coordinate plane?

• As angles

• As ordered pairs

• As line segments

• As curves

What is the first step in plotting a polygon on a coordinate plane?

• Calculating the area

• Connecting the points in any order

• Labeling the vertices

• Drawing random lines

What is necessary to calculate the perimeter of a polygon on a coordinate plane?

• The color of the polygon

• The distance between points

• The number of vertices

• The area of the polygon

In the example of Tommy's walk, what is the total distance he walked?

• 25 blocks

• 22 blocks

• 30 blocks

• 15 blocks

What is the 'fancy' way to find the perimeter on a coordinate plane?

• Using a ruler

• Guessing the length

• Counting the blocks

• Using distance formulas

How do you find the area of a rectangle on a coordinate plane?

• By adding all sides

• By multiplying length and width

• By using the perimeter

• By counting the vertices

What is the formula for the area of a trapezoid?

• Length times width

• Sum of all sides

• Base times height

• One half height times base one plus base two

What should you do if you don't have a formula for a polygon's area?

• Guess the area

• Use the perimeter

• Break it into known shapes

• Ignore the problem

What is the area of the polygon in the final example?

• 24 square units

• 32 square units

• 40 square units

• 16 square units
