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 properties of a square?

Back

A square is a polygon with four equal sides and four right angles.

Front

How do you calculate the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × base × height.

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 coordinates of a point on the coordinate plane?

Back

The coordinates of a point are given as (x, y), where 'x' is the horizontal distance from the origin and 'y' is the vertical distance from the origin.

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

How do you determine if four points form a rectangle?

Back

Four points form a rectangle if the opposite sides are equal in length and all angles are right angles.

Front

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

Back

The distance between two points is calculated using the formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point (0, 0) on the coordinate plane where the x-axis and y-axis intersect.
