Polygons on a Coordinate Plane

Front

What is a polygon?

Back

A polygon is a closed figure made up of straight line segments. Examples include triangles, rectangles, and pentagons.

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).

How do you find the perimeter of a rectangle?

Back

To find the perimeter of a rectangle, add the lengths of all four sides or use the formula: P = 2(length + width).

Front

What is the distance formula for two points (x1, y1) and (x2, y2)?

Back

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²).

Front

What are the coordinates of a point?

Back

Coordinates are a pair of numbers (x, y) that define the position of a point on a coordinate plane.

Front

What is the length of a side of a rectangle?

Back

The length of a side of a rectangle is the distance between two adjacent vertices.

Front

How do you identify the fourth vertex of a rectangle given three vertices?

Back

To find the fourth vertex, use the properties of rectangles: opposite sides are equal and parallel.

Front

What is the difference between length and width in a rectangle?

Back

Length is the longer side of the rectangle, while width is the shorter side.

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width: A = length × width.

Front

What does it mean for points to be collinear?

Back

Collinear points are points that lie on the same straight line.
