What is the perimeter of a polygon?

Back

The perimeter of a polygon is the total distance around the polygon, calculated by adding the lengths of all its sides.

Front

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

Back

Coordinates are given as an ordered pair (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does the x-coordinate represent in a coordinate pair?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent in a coordinate pair?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

Front

How do you determine the opposite y-coordinate of a point?

Back

To find the opposite y-coordinate, change the sign of the original y-coordinate.

Front

How do you plot a point given its coordinates?

Back

To plot a point, start at the origin (0,0), move horizontally to the x-coordinate, and then vertically to the y-coordinate.

Front

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

Back

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