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 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 distance between two points on a coordinate plane?

Back

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

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 are the four quadrants of the coordinate plane?

Back

Quadrant I: (+,+), Quadrant II: (-,+), Quadrant III: (-,-), Quadrant IV: (+,-).

Front

How do you identify the coordinates of a point?

Back

Coordinates are written as (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

How do you determine which quadrant a point is in?

Back

Look at the signs of the x and y coordinates: (+,+) is Quadrant I, (-,+) is Quadrant II, (-,-) is Quadrant III, (+,-) is Quadrant IV.

Front

What does it mean for a point to be on the x-axis?

Back

A point is on the x-axis if its y-coordinate is 0, written as (x, 0).

Front

What does it mean for a point to be on the y-axis?

Back

A point is on the y-axis if its x-coordinate is 0, written as (0, y).
