Drawing and identifying a polygon in the coordinate plane
In this lesson we are given the coordinates of points in a coordinate plane.
Joining these points with line segments we get a polygonal figure. We are required to identify the polygon so formed.
Plot the following points (-5, 3) (3,3) (-5,-3) in the coordinate plane. Join the points with line segments and identify the polygonal figure so formed.
We know that in a coordinate plane, a positive number tells us to move right or up and a negative number tells us to move left or down.
To locate (-5, 3) (3,3) (-5,-3) points
Point (-5, 3): The x coordinate is -5 so we move left 5 units on x axis from origin and since y coordinate 3 is positive, we move up 3 units to locate point (-5, 3):
Similarly, the other two points (3,3) (-5,-3) are located.
Joining the three points with line segments, we see that we get a triangle as shown below.
Identify the polygon formed by the points in the coordinate plane below
There are five points in the given coordinate plane.
Joining these points with line segments, the polygon formed has five sides and is a Pentagon.
