What is a synonym for ordered pairs?
One such synonym would be coordinates, which is also the proper way of naming the ordered pairs on a Cartesian coordinate plane.
What is a close plane figure?
A plane figure is one that is entirely in one plane. One way to think of that is it can be made to lie flat - no ups or downs. A closed figure is one where you can go around the outside of the figure and return to your starting point - without jumping. If you take any two points - one inside the figure and one outside, then you cannot draw a curve from one to the other without crossing the boundary of the figure.
Rotate do you rotate a figure 270 degrees counterclockwise?
270 degrees is 3/4 of the way around the circle. Ir is the same as rotating it 90 degrees (1/4) of the way clockwise. Turn it so anything that was pointing straight up would be pointing to the right.
What plane figure describes the shape of a rectangular?
Rectangular is an adjective and so there is no noun in the question.To put it another way, a rectangular what?
How do you reflect a figure around the origin?
The best way is this:Draw a line from the point closest to the origin to the actual origin. Rotate the line however many degrees you are told, whichever way you are told. After you have the point closest to the origin rotated, you can either rotate the other points the same way or just draw them in based on where the other point lies.Another way, sort of the cheater way, is to just take a piece of tracing paper and trace the figure onto it. Hold it down by pressing your pencil on the tracing paper where the origin is, and rotating it however many degrees, whichever way you are told.This is for ROTATE. To reflect just use the opposite signs on the coordinates.
