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 length of a side of a rectangle on a coordinate plane?

Back

To find the length of a side, subtract the x-coordinates (or y-coordinates) of the endpoints of that side.

Front

What is the formula for the distance between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

How can you determine if three points form a triangle?

Back

Three points form a triangle if they are not collinear (not on the same straight line).

Front

What is the significance of the fourth vertex in a rectangle?

Back

The fourth vertex completes the rectangle and can be found using the coordinates of the other three vertices.

Front

What does it mean for points to be collinear?

Back

Collinear points are points that lie on the same straight line.

Front

How do you identify the coordinates of a point on a coordinate plane?

Back

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

Front

What is the relationship between the sides of a square?

Back

All sides of a square are equal in length, and all angles are right angles.
