Coordinate Plane - Polygon

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). Each point on the plane is defined by an ordered pair of numbers (x, y).

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. Examples include triangles, quadrilaterals, and pentagons.

Front

How do you find the area of a polygon?

Back

The area of a polygon can be calculated using various formulas depending on the type of polygon. For rectangles, it's length times width; for triangles, it's 1/2 base times height.

Front

What is the formula for the perimeter of a polygon?

Back

The perimeter of a polygon is the sum of the lengths of all its sides.

Front

What are coordinates?

Back

Coordinates are a set of values that show an exact position on a coordinate plane, typically represented as (x, y).

Front

What is the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair (x, y) and represents the horizontal position on the coordinate plane.

Front

What is the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair (x, y) and represents the vertical position on the coordinate plane.

Front

How do you calculate the distance between two points on a coordinate plane?

Back

The distance between two points (x1, y1) and (x2, y2) can be calculated using the formula: √((x2 - x1)² + (y2 - y1)²).

Front

What is a rectangle?

Back

A rectangle is a polygon with four sides and four right angles, where opposite sides are equal in length.

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point (0, 0) on a coordinate plane where the x-axis and y-axis intersect. It serves as the reference point for all other points.
