Polygons on 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 are the properties of a rectangle?

Back

A rectangle has four sides, opposite sides are equal in length, and all angles are right angles (90 degrees).

Front

How do you find the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height.

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

How do you find the area of a triangle?

Back

Area = 1/2 × base × height.

Front

What are coordinates in the coordinate plane?

Back

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

Front

What is the longest side of a rectangle with coordinates (3, 2), (-2, 2), (-2, -1), (3, -1)?

Back

5 units.

Front

What is the area of a rectangle with a length of 6 units and a width of 4 units?

Back

24 square units.

Front

How do you calculate the area of a polygon with vertices?

Back

Use the formula: Area = 1/2 × |Σ (x_i * y_(i+1) - x_(i+1) * y_i)| for vertices (x_i, y_i).
