Polygons on a Coordinate Plane

Front

What is a polygon?

Back

A polygon is a closed figure made up of straight line segments. Examples include triangles, rectangles, and pentagons.

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).

Front

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

Back

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

Front

What is the length of the shortest side of a rectangle?

Back

The shortest side of a rectangle is the smaller of the two lengths of its sides.

Front

How do you identify a point on a coordinate plane?

Back

A point is identified by its coordinates (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What are the coordinates of point D?

Back

Point D is located at (8, 5).

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

How do you find the length of a line segment?

Back

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

Front

What is a rectangle?

Back

A rectangle is a polygon with four sides and four right angles.

Front

What are the properties of a rectangle?

Back

Opposite sides are equal in length, and all angles are right angles.
