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 perimeter of a polygon?

Back

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

Front

What are the coordinates of a point?

Back

Coordinates are a pair of numbers (x, y) that define the position of a point on a coordinate plane.

Front

How do you identify the fourth vertex of a rectangle given three vertices?

Back

Use the properties of rectangles: the fourth vertex can be found by ensuring opposite sides are equal and parallel.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

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

Back

The x-axis is the horizontal line, and the y-axis is the vertical line; together they form the coordinate plane.

Front

How do you determine if a shape is a polygon?

Back

A shape is a polygon if it is closed, has straight sides, and does not intersect itself.

Front

What is the distance between the points (0, 6) and (0, -4)?

Back

The distance is 10 units.
