Coordinate Plane, Distance, Polygons

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs.

Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

A pair of numbers (x, y) that represent a point on the coordinate plane, where 'x' is the horizontal position and 'y' is the vertical position.

The point (0, 0) where the x-axis and y-axis intersect.

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

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

The total distance around the polygon, calculated by adding the lengths of all its sides.

The x-axis is the horizontal line on the coordinate plane, while the y-axis is the vertical line.

Both x and y coordinates are positive.

By reading the x-value (horizontal) first and the y-value (vertical) second from the origin.
