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 happens to the coordinates of a point when it is reflected across the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

What is the formula to calculate the perimeter of a rectangle?

Back

Perimeter = 2(length + width).

Front

How do you determine the area of a rectangle?

Back

Area = length × width.

Front

What are the coordinates of the origin on a coordinate plane?

Back

The origin is at the point (0, 0).

Front

What is the significance of the x-axis and y-axis on a coordinate plane?

Back

The x-axis is the horizontal line, and the y-axis is the vertical line that intersect at the origin, dividing the plane into four quadrants.

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 distance between the points (3, 4) and (3, 1)?

Back

The distance is 3 units.
