4.7 Polygons on the Coordinate Plane Class Practice

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments connected end to end.

Front

What are the characteristics of a rectangle?

Back

A rectangle is a polygon with four sides, where opposite sides are equal in length and all angles are right angles (90 degrees).

Front

How do you find the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, use the ordered pair (x, y), where 'x' is the horizontal distance from the origin and 'y' is the vertical distance.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What is the area of a polygon?

Back

The area of a polygon is the amount of space enclosed within its sides.

Front

How do you calculate the perimeter of a polygon?

Back

To calculate the perimeter, add the lengths of all the sides of the polygon.

Front

What is the significance of vertices in polygons?

Back

Vertices are the points where two sides of a polygon meet.
