Polygons on a Coordinate Plane-Practice 1

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 calculate the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width).

Front

What is the formula for the area of a rectangle?

Back

Area = length * width.

Front

What are coordinates in a coordinate plane?

Back

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

Front

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

Back

Length = |x2 - x1| or |y2 - y1|, depending on the orientation.

Front

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

Back

The fourth corner can be found using the coordinates of the other three corners to ensure the shape is a rectangle.

Front

What does it mean for a shape to be 'closed'?

Back

A closed shape means that all the line segments connect back to the starting point, enclosing an area.

Front

How do you determine if a shape is a rectangle based on its corners?

Back

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

Front

What is the difference between units and units squared?

Back

Units measure length, while units squared measure area.
