6.7.5-MINI - Polygons in 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 properties of a rectangle?

Back

A rectangle has four right angles, opposite sides that are equal in length, and the diagonals are equal in length.

Front

How do you find the length of a side of a rectangle given its coordinates?

Back

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

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

How do you determine if four points form a rectangle?

Back

Check if opposite sides are equal and if all angles are right angles.

Front

What is the distance between the points (3, 2) and (-2, 2)?

Back

Distance = 5 units.

Front

What is the area of a rectangle with length 5 units and width 3 units?

Back

Area = 5 × 3 = 15 square units.

Front

What is the perimeter of a rectangle with length 4 units and width 3 units?

Back

Perimeter = 2 × (4 + 3) = 14 units.

Front

What coordinates could form a rectangle with the points (3, 2), (-2, 2), and (-2, -1)?

Back

(3, -1) could be the fourth point.
