Drawing Polygons Using Coordinates

This video tutorial teaches how to draw polygons using given coordinates as vertices. It begins with an introduction to the coordinate plane, explaining the x-axis and y-axis, and how they divide the plane into quadrants. The tutorial emphasizes the importance of understanding ordered pairs and their representation on the axes. Through examples, it demonstrates plotting points to form shapes like a rhombus and a pentagon, highlighting the process of connecting vertices to visualize the polygon. The lesson concludes with a recap of the skills learned in plotting and identifying polygons.

What is the role of the first number in an ordered pair on a coordinate plane?

• It represents the quadrant number.

• It indicates the position along the x-axis.

• It indicates the position along the y-axis.

• It shows the distance from the origin.

When plotting the point (4, -3), in which direction do you move along the y-axis?

• Down 3 units

• Up 3 units

• Right 3 units

• Left 3 units

What shape is formed by the points (-4, 8), (-9, 3), (1, 3), and (-4, -2)?

• Square

• Rectangle

• Triangle

• Rhombus

How many vertices does a pentagon have?

• Five

• Four

• Seven

• Six

Which of the following sets of points will form a pentagon?

• (2, 5), (7, 1), (5, -5), (-1, -5), (-3, 1)

• (5, 5), (6, 6), (7, 7), (8, 8)

• (1, 1), (2, 2), (3, 3), (4, 4), (5, 5)
