Coordinate Plane, Distance, Polygons

Front

What is the coordinate plane?

Back

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.

Front

What are the four quadrants of the coordinate plane?

Back

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

Front

What is an ordered pair?

Back

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.

Front

What is the origin in the coordinate plane?

Back

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

Front

How do you find the distance between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is a polygon?

Back

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

Front

What is the perimeter of a polygon?

Back

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

Front

What is the difference between the x-axis and y-axis?

Back

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

Front

What are the coordinates of the point in Quadrant I?

Back

Both x and y coordinates are positive.

Front

How do you identify the coordinates of a point on the coordinate plane?

Back

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