Polygons in the Coordinate Plane Worksheets

What Are Polygons? Look around you; you see different objects with different shapes. Some are perfectly equal while others are peculiar. Pick a square. Can you see how its lines are equal and closed at every end? Now take a rectangle or a triangle. They all have equal sides and closed ends. They are called polygons. In simple words, any flat figure that is enclosed, made of straight lines, has more than three sides and has many angles is known as a polygon. The sides are identified with the name the polygon has been given. For example, a triangle is a 3-sided polygon. A square is a 4-sided polygon. A pentagon has 5-sides, a hexagon has 6-sides and so on. Like many other shapes, polygons can be regular and irregular. Regular Polygons - When the sides in a polygon are equal, and the number of angles is equal to the number of lines, it is called a regular polygon. Irregular Polygons - But when a polygon's sides don't match, and the angles are not the same, the polygon is known as an irregular polygon.

Homework Sheets

We start with an outline and find the distance between points. We then bring it to life by making them real.

• Homework 1 - If the points on the coordinate plane below are the three vertices of a rectangle, coordinate the fourth vertex.
• Homework 2 - How do you know? What are the length and width of the rectangle?
• Homework 3 - Find the area of the given figure.

Practice Worksheets

I purposely threw perimeter in here to help the kids focus on the distance between the points and its meaning.

• Practice 1 - Represent the locations as points on a coordinate grid with a unit of 1 mile. What shape might you make if you connect the points on the grid?
• Practice 2 - Find the area of the shape formed. Find the perimeter of the shape formed.
• Practice 3 - Which shape forms between these four icons?
