Polygons on the Coordinate Plane

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 has four sides, opposite sides are equal in length, and all angles are right angles (90 degrees).

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).

Front

What is the coordinate plane?

Back

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

Front

What does the origin represent in the coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the ordered pair (0,0).

Front

How do you find the length of a line segment between two points?

Back

Use the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is a vertex in a polygon?

Back

A vertex is a point where two sides of a polygon meet.

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated by adding the lengths of all sides: Perimeter = 2(length + width).

Front

How can you determine if four points form a rectangle?

Back

Check if opposite sides are equal and if all angles are right angles.

Front

What is the significance of ordered pairs in the coordinate plane?

Back

Ordered pairs (x, y) represent the position of a point on the coordinate plane.
